Hmmm, most likely I made some mistake - I'll double check and report back. -- Fernando -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I'll have to rebuild. I'm doing full rpm package builds or a build server and the original build tree is gone. -- Fernando -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Argh, something's wrong with what I did, I'm looking at the source in the build server and it appears to not be patched (but I saw it being patched in the logs with no error? go figure...). -- Fernando -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Let's see if I can fudge a threaded reply. ================================================ I also have some nfs issues with this combo, but not as severe. Maybe my fstab mount options help: noauto,users,rsize=4096,wsize=4096,timeo=14,intr,hard Anyway, Fedora 13,both vanilla 2.6.33.5 and Redhat patched, exhibit it as a kernel fault upon user mounting a nfs partition. It is the uniprocessor variant kernel (not PAE). I get an operating nfs connection, but the kernel auto bug reporting thingy (abrt) pops up shortly after the mount. I was going to work through a few variations on kernels etc before trying bugzilla but I've acquired a bug of the non-computer variety and won't feel up to this for a week or so.

Finally... I did a local build in my desktop machine so I now have access to the full patched/compiled source tree. I confirmed that the patch you sent is there (moving a spin_lock one line down). This is from a different kernel (non-PAE) so the exact address is different from the previous report: (gdb) list *0xc04d82dd 0xc04d82dd is in d_materialise_unique (fs/dcache.c:2100). 2095 spin_lock(&aparent->d_lock); 2096 spin_lock(&dparent->d_lock); 2097 spin_lock(&dentry->d_lock); 2098 spin_lock(&anon->d_lock); 2099 2100 dentry->d_parent = (aparent == anon) ? dentry : aparent; 2101 list_del(&dentry->d_u.d_child); 2102 if (!IS_ROOT(dentry)) 2103 list_add(&dentry->d_u.d_child, &dentry->d_parent->d_subdirs); 2104 else See below for the full dump of the BUG through the serial console in this particular occurrence. Let me know if there is anything else I could do. -- Fernando ------------[ cut here ]------------ kernel BUG at kernel/rtmutex.c:808! invalid opcode: 0000 [#1] PREEMPT SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1c.5/0000:02:00.0/net/eth0/statistics/collisions Modules linked in: fuse autofs4 act_police cls_flow cls_fw cls_u32 sch_htb sch_hfsc sch_ingress sch_sfq xt_time xt_connlimit xt_realm iptable_raw xt_comment xt_recent xt_policy ipt_ULOG ipt_REDIRECT ipt_NETMAP ipt_MASQUERADE ipt_ECN ipt_ecn ipt_CLUSTERIP ipt_ah ipt_addrtype nf_nat_tftp nf_nat_snmp_basic nf_nat_sip nf_nat_pptp nf_nat_proto_gre nf_nat_irc nf_nat_h323 nf_nat_ftp nf_nat_amanda ts_kmp nf_conntrack_amanda nf_conntrack_sane nf_conntrack_tftp nf_conntrack_sip nf_conntrack_proto_sctp nf_conntrack_pptp nf_conntrack_proto_gre nf_conntrack_netlink nf_conntrack_netbios_ns nf_conntrack_irc nf_conntrack_h323 nf_conntrack_ftp xt_TPROXY nf_tproxy_core xt_tcpmss xt_pkttype xt_physdev xt_owner xt_NFQUEUE xt_NFLOG nfnetlink_log xt_multiport xt_MARK xt_mark xt_mac xt_limit xt_length xt_iprange xt_helper xt_hashlimit xt_DSCP xt_dscp xt_dccp xt_CONNMARK xt_connmark xt_CLASSIFY ipt_LOG iptable_nat nf_nat iptable_mangle nfnetlink coretemp hwmon_vid nfs lockd fscache nfs_acl auth_rpcgss sunrpc cpufreq_ondemand acpi_cpufreq ip6t_REJECT nf_conntrack_ipv6 ip6table_filter ip6_tables ipv6 dm_multipath uinput snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_ice1712 snd_ice17xx_ak4xxx snd_ak4xxx_adda snd_seq_dummy snd_cs8427 snd_ac97_codec iTCO_wdt snd_seq_oss snd_seq_midi_event snd_seq snd_pcm_oss snd_mixer_oss snd_pcm iTCO_vendor_support ac97_bus snd_i2c snd_mpu401_uart snd_rawmidi snd_seq_device snd_timer i2c_i801 snd ohci1394 snd_page_alloc soundcore asus_atk0110 joydev sky2 serio_raw sata_sil24 radeon ttm drm_kms_helper drm i2c_algo_bit i2c_core [last unloaded: microcode] Pid: 2832, comm: nautilus Not tainted 2.6.33.6-147.rt23.3.fc12.ccrma.i686.rt #1 P5K/EPU/P5K/EPU EIP: 0060:[<c0780ab7>] EFLAGS: 00010046 CPU: 0 EIP is at rt_spin_lock_slowlock+0x43/0x1bb EAX: f21522b0 EBX: f022f7a4 ECX: f022f7a4 EDX: f21522b0 ESI: efcf9f1c EDI: f022fd3c EBP: f23b7d14 ESP: f23b7cbc DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 preempt:00000001 Process nautilus (pid: 2832, ti=f23b6000 task=f21522b0 task.ti=f23b6000) Stack: 00000000 00000001 00000000 f23b7cd8 00000292 efcab7ac 00000000 f23b7d1c <0> fab0f5e6 00000246 f022f7a4 f022f79c 00000000 f23b7cfc c045e4cb efcab7ac <0> 00000000 c0781206 00000246 f022f7a4 efcf9f1c f022fd3c f23b7d20 c045e501 Call Trace: [<fab0f5e6>] ? nfs_refresh_inode_locked+0x79c/0xa1e [nfs] [<c045e4cb>] ? rt_spin_lock_fastlock.clone.1+0x26/0x5f [<c0781206>] ? rt_spin_unlock+0x8/0xa [<c045e501>] ? rt_spin_lock_fastlock.clone.1+0x5c/0x5f [<c07811f2>] ? rt_spin_lock+0x8/0xa [<c04d82dd>] ? d_materialise_unique+0xbf/0x29e [<fab0c5a0>] ? nfs_do_filldir+0x27b/0x3a9 [nfs] [<c04d5490>] ? filldir64+0x0/0xcb [<fab0cd57>] ? nfs_readdir+0x689/0x707 [nfs] [<c04d5490>] ? filldir64+0x0/0xcb [<c0424e61>] ? enqueue_task+0x70/0x80 [<fab1d0de>] ? nfs3_decode_dirent+0x0/0x10e [nfs] [<c045d24e>] ? do_futex+0x99/0x696 [<c0780e85>] ? rt_mutex_lock_killable+0x28/0x2c [<c04d574a>] ? vfs_readdir+0x66/0x92 [<c04d5490>] ? filldir64+0x0/0xcb [<c04d57d9>] ? sys_getdents64+0x63/0xa5 [<c0476d3f>] ? audit_syscall_entry+0x113/0x135 [<c040321f>] ? sysenter_do_call+0x12/0x28 Code: 7b 08 00 89 45 b8 75 12 8d 43 04 89 43 04 89 43 08 8d 43 0c 89 43 0c 89 43 10 8b 43 14 64 8b 15 7c d4 a3 c0 83 e0 fc 39 c2 75 04 <0f> 0b eb fe 8b 3a 81 ff 08 01 00 00 74 0a 83 ff 02 b8 04 00 00 EIP: [<c0780ab7>] rt_spin_lock_slowlock+0x43/0x1bb SS:ESP 0068:f23b7cbc ---[ end trace 21aa2c1d673e60c7 ]--- note: nautilus[2832] exited with preempt_count 1 BUG: soft lockup - CPU#2 stuck for 61s!
