[parisc-linux] [BUG] XFS broken (again) on parisc

[Thibaut VARENE]

Hi,

What I initially believed to be related to the SCSI offlining problems
we had seems to be more complex than that: I can reliably kill any XFS
filesystem with current GIT TOB by just unmouting and remounting, no
matter if there's any activity on the fs.

The remount attempt will yield:

XFS mounting filesystem sdb1
XFS: Log inconsistent (didn't find previous header)
XFS: failed to find log head
XFS: log mount/recovery failed: error 5
XFS: log mount failed
mount: /dev/sdb1: can't read superblock

At this point, the fileystem is totally corrupted (I'm still running
xfs_repair, but have very little hope given the incredible amount of
errors detected on a fs that's been mounted for about 10s without any
activity on it before I tried to unmount/remount it)...

That happens on 64bit SMP. I'll investigate more later on. According
to Guy Martin, this doesn't  happen on UP kernels.

HTH
