I am not sure what was a change but yes it was IRQ mapping issue at pci subsystem of OS. So my suggestion to you is use 2.6.34 where things are working fine and see what a behavior is with 3.04.14 driver and 3.04.15 driver. ~Kashyap > mptbase: ioc0: Initiating bringup > ioc0: LSISAS1064 A3: Capabilities={Initiator} > mptbase: ioc0: WARNING - Issuing Reset from mpt_config!! > mptbase: ioc0: Attempting Retry Config request type 0x1, page 0x2, > action 0 > mptbase: ioc0: WARNING - Issuing Reset from mpt_config!! > mptbase: ioc0: Initiating recovery > mptbase: ioc0: Attempting Retry Config request type 0x1, page 0x2, > action 0 > > > > Where as 2.6.34 with the same .config boots fine: > > Fusion MPT SAS Host driver 3.04.14 > mptsas 0000:03:04.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 > mptbase: ioc0: Initiating bringup > ioc0: LSISAS1064 A3: Capabilities={Initiator} > scsi0 : ioc0: LSISAS1064 A3, FwRev=01125400h, Ports=1, MaxQ=511, IRQ=19 > mptsas: ioc0: attaching ssp device: fw_channel 0, fw_id 0, phy 0, > sas_addr 0x5000c500021cbc49 > scsi 0:0:0:0: Direct-Access IBM-ESXS ST973401SS B51D PQ: 0 > ANSI: 5 > sd 0:0:0:0: Attached scsi generic sg0 type 0 > Fusion MPT misc device (ioctl) driver 3.04.14 > sd 0:0:0:0: [sda] 143374000 512-byte logical blocks: (73.4 GB/68.3 GiB) > sd 0:0:0:0: [sda] Write Protect is off > sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, supports > DPO and FUA > mptctl: Registered with Fusion MPT base driver > mptctl: /dev/mptctl @ (major,minor=10,220) > ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver > ACPI: PCI Interrupt Link [LPUS] enabled at IRQ 5 > ehci_hcd 0000:00:03.2: PCI INT A -> Link[LPUS] -> GSI 5 (level, low) -> > IRQ 5 > ehci_hcd 0000:00:03.2: EHCI Host Controller > ehci_hcd 0000:00:03.2: new USB bus registered, assigned bus number 1 > sda: sda1 sda2 sda3 sda4 > ... > > > Although from the warning, this may be irq routing related, not driver > related.
