Title:
XFS: Corruption of in-memory data detected
Status in linux package in Ubuntu:
Incomplete
Bug description:
I've got 2 NFS servers that have been running Ubuntu 12.04 for a
number of years. For the last 9 months or so they've been happily
running kernel 3.8.0-44 with no problem. As soon as I upgraded them to
3.13.0-53 the both experienced the same problem on an XFS filesystem
when it started to have a heavy write load:
[267127.795322] XFS (sda1): Internal error xfs_attr3_leaf_write_verify at
line 216 of file /build/buildd/linux-lts-trusty-3.13.0/fs/xfs/xfs_attr_leaf.c.

I've not been able to reproduce this on demand outside our production
workload. Downgrading the machines back to 3.8.0-44 has returned us to
stability.
