So you oops when dereferencing that pgd value in %rax (%rdx in my case), *pgd in pgd_none_or_clear_bad(pgd) which is called in the below fragment of unmap_page_range(). pgd = pgd_offset(vma->vm_mm, addr); do { next = pgd_addr_end(addr, end); if (pgd_none_or_clear_bad(pgd)) { (*zap_work)--; continue; } next = zap_pud_range(tlb, vma, pgd, addr, next, zap_work, details); } while (pgd++, addr = next, (addr != end && *zap_work > 0)); so it looks like it tries to find a page table rooted at that address but the pointer value of 0000000000002203 is bogus. Which might be because when we iterate over the vmas in unmap_vmas, one of those vma->vm_start is invalid... -- Regards/Gruss, Boris. -- 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/

The same is true at the end: another large constant is cut off in the middle. The byte just before the dumped instruction stream is almost certainly '48h', and the last byte of the last constant is 0xff, and the disassembly ends up being: 0: 48 b8 00 00 00 00 80 mov $0xffffff8000000000,%rax 7: ff ff ff a: 48 21 45 80 and %rax,-0x80(%rbp) e: 48 8b 45 80 mov -0x80(%rbp),%rax 12: 48 ff c8 dec %rax 15: 48 3b 85 40 ff ff ff cmp -0xc0(%rbp),%rax 1c: 48 8b 85 50 ff ff ff mov -0xb0(%rbp),%rax 23: 48 0f 42 7d 80 cmovb -0x80(%rbp),%rdi 28: 48 89 7d 80 mov %rdi,-0x80(%rbp) 2c:* 48 8b 38 mov (%rax),%rdi <-- trapping instruction 2f: 48 85 ff test %rdi,%rdi 32: 0f 84 f5 04 00 00 je 0x52d 38: 48 b8 fb 0f 00 00 00 mov $0xffffc00000000ffb,%rax 3f: c0 ff ff But yes, you found the right spot (that 0xffffff8000000000 constant is -549755813888 decimal): > which I could correlate with what I get here (comments added): Yup. Close enough. Btw, it's often good to look at both the *.s code _and_ the *.lst code. If you do "make mm/memory.lst", you'll find those big constants easily, and then you'll see the code this way: do { next = pgd_addr_end(addr, end); ffffffff81b2aa45: 48 b8 00 00 00 00 80 mov $0x8000000000,%rax ffffffff81b2aa4c: 00 00 00 ffffffff81b2aa4f: 49 8d 04 04 lea (%r12,%rax,1),%rax ffffffff81b2aa53: 48 89 45 a8 mov %rax,-0x58(%rbp) ffffffff81b2aa57: 48 b8 00 00 00 00 80 mov $0xffffff8000000000,%rax ffffffff81b2aa5e: ff ff ff ffffffff81b2aa61: 48 21 45 a8 and %rax,-0x58(%rbp) ffffffff81b2aa65: 48 8b 45 b8 mov -0x48(%rbp),%rax ffffffff81b2aa69: 48 8b 55 a8 mov -0x58(%rbp),%rdx ffffffff81b2aa6d: 48 ff c8 dec %rax ffffffff81b2aa70: 48 ff ca dec %rdx ffffffff81b2aa73: 48 39 c2 cmp %rax,%rdx ffffffff81b2aa76: 48 8b 45 b8 mov -0x48(%rbp),%rax ffffffff81b2aa7a: 48 8b 55 90 mov -0x70(%rbp),%rdx ffffffff81b2aa7e: 48 0f 42 45 a8 cmovb -0x58(%rbp),%rax ffffffff81b2aa83: 48 89 45 a8 mov %rax,-0x58(%rbp) ffffffff81b2aa87: 48 8b 02 mov (%rdx),%rax void pud_clear_bad(pud_t *); void pmd_clear_bad(pmd_t *); static inline int pgd_none_or_clear_bad(pgd_t *pgd) { if (pgd_none(*pgd)) ffffffff81b2aa8a: 48 85 c0 test %rax,%rax ffffffff81b2aa8d: 74 20 je ffffffff81b2aaaf <unmap_vmas+0x228> return 1; if (unlikely(pgd_bad(*pgd))) { ffffffff81b2aa8f: 48 ba fb 0f 00 00 00 mov $0xffffc00000000ffb,%rdx ffffffff81b2aa96: c0 ff ff ffffffff81b2aa99: 48 21 c2 and %rax,%rdx ffffffff81b2aa9c: 48 83 fa 63 cmp $0x63,%rdx ffffffff81b2aaa0: 0f 84 d9 04 00 00 je ffffffff81b2af7f <unmap_vmas+0x6f8> although Parag's compiler has generated much better code (possibly due to config differences, possibly due to compiler versions) > So you oops when dereferencing that pgd value in %rax (%rdx in my case), > *pgd in pgd_none_or_clear_bad(pgd) which is called in the below fragment > of unmap_page_range(). > > pgd = pgd_offset(vma->vm_mm, addr); > do { > next = pgd_addr_end(addr, end); > if (pgd_none_or_clear_bad(pgd)) { > (*zap_work)--; > continue; > } > next = zap_pud_range(tlb, vma, pgd, addr, next, > zap_work, details); > } while (pgd++, addr = next, (addr != end && *zap_work > 0)); Correct. > so it looks like it tries to find a page table rooted at that address > but the pointer value of 0000000000002203 is bogus. Yes, it does look like some strange page table corruption, doesn't look anon_vma related at all. It's intriguing that it started happening now, though, so..

But yeah, now that I'm looking at show_registers(), we don't start dumping on precise instruction boundary but simply 64 bytes in the default case. No time for an instruction decoder along that path :). > > which I could correlate with what I get here (comments added): > > Yup. Close enough.

Well, Parag said something about kexec kernel so it is definitely interesting what he means there - a kexec-enabled kernel or is this the "second" kernel his machine kexec'd into after a previous failure. I think this could clarify the situation a bit.
