OK, it repeatedly hits a BUG() during startup (after detecting the first
two hard drives on the Primary IDE channel, it takes an interrupt and then
during that context calls detect_ide_disk_speed or something like that,
which then calls _kmem_cache_alloc during said interrupt context,
resulting in the stack printout and traceback, then it continues). Second
problem is that as soon as I started up /dev/md0, a raid1 array that was
dirty due to all the failed boots, it almost immediately hard locks the
system. That could be a raid1 hardlock, or it could be a serverworks or
generic ide code lockup. Important details would be that the two mirror
disks for /dev/md0 are on ide0 and ide1 so a rebuild would generate lots
of primary/secondary controller parallel traffic.
I didn't provide a lot of details before because this machine doesn't have
a serial console host to grab logs and I didn't write all the stuff down.
Then there is the additional fubar stuff but it's mainly in the category
of "Red Hat Linux 8.0 made initrd images using nash as the shell blow
chunks in regards to actually working with the 2.5.40 kernel, failing
simple operations such as mounting /proc, which of course causes damn near
everything else it tries to do to fail since the normal /proc files aren't
available".
