Hi,

Yesterday a Linux PostgreSQL server spontaneously rebooted after a few
minutes of high I/O wait.  The kernel log reported a number of errors
related to the XFS filesystem backing the databases.

Here is the uname -a: Linux pg01 3.2.0-4-amd64 #1 SMP Debian
3.2.46-1+deb7u1 x86_64 GNU/Linux

The filesystem in question is XFS running on top of an LVM2 logical
volume over SSDs.  There was no indication of a hardware failure.

Relevant kernel error messages are below. I would appreciate thoughts
on whether this is a known bug, and whether it would be advisable to
upgrade to a newer kernel version.

TIA,

Galen
