Looks like we have a bad src page when doing the memcpy(): memcpy: 48 89 f8 mov %rdi,%rax 48 89 d1 mov %rdx,%rcx <f3>a4 rep movsb %ds:(%rsi),%es:(%rdi) // e.g. rep on *rdi++ = *rsi++ c3 retq
The GPF flags 0000 means page read and not found. rsi is 0005080000000000 (src) and the rdi looks valid (ffff88008ba80156) ..and the memcpy from extent_io: was: kaddr = page_address(page); memcpy(dst, kaddr + offset, cur); so it appears that the page kaddr from page is wrong somehow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1384711 Title: btrfs oops on current 3.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1384711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
