SubjectRe: kernel oops with 2.4.3-xfs
Date
From

Hmm, we 'released' version 1 of XFS against a 2.4.2 base - and packaged
it into a RedHat 7.1 Kernel RPM, we also have a development CVS tree
currently running at 2.4.4. If you are running a production server
with what you describe below, you might want to switch to one of the
other two kernels I mentioned. The development tree just got a fix
which does make xfs much more responsive to cache pruning, and has
numerous other xfs fixes so you might want to use this.
