I decided to check with RedHat, which I should have done in the first
place, and I found this:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=56603
I haven't tested the mem=800M fix (I have 1G), but since the kernel is
now way past 2.4.9, should I care about a fix? 2.4.14-SGI_XFS_1.0.2 is
working fine for me right now, so I'm assuming that this *might* be
better than running 2.4.3-SGI_XFS_1.0.1.
Does anybody know where I can find a list of RedHat's
improvements/fixes/hacks to the stock kernels? I'd really like to know
if there are any compelling reasons to track their kernels, or just go
with the latest SGI_XFS RPMS.
