Mine were from 2.4.9-ac10 + ext3-0.9.9 + ext3 speedup patch (which is in
0.9.10) + "experimental VM patch" (see the ext3 for 2.4 page) + jfs-1.0.4
(compiled with gcc 2.96-85, romfs initrd, everything possible as modules)

I've booted two of our servers into 2.4.9-ac18 compiled with egcs-1.1.2
(so far without Trond's patches) and will report anything odd.

Incidentally a third server on my 2.4.9-ac10 things has oopsed (output
below). What these three servers have in common is that they're all using
ICP-Vortex gdth raid arrays, and no IDE. I have four or five other setups
with the exact same kernel (well, two of them compiled for UP Athlon
rather than SMP Coppermine) with IDE root and further SCSI partitions
(some aic7xxx, some gdth) which have all been very stable. We haven't
ruled out a cabling/termination problem, but it's a bit spooky.

Thanks for the responses :)
