I 'm the maintainer of Trinity Rescue Kit and I try to make kernels as
generic as possible, supporting the most possible hardware. So I compile
about any disk and nic driver. Processor arch is generic 586.
Here 's the command with which I made 2.6.19 crash.
'for i in *; do i=`echo $i | cut -d . -f 1`; echo $i; modprobe $i; rmmod
$i; done'
< all sata is static in the kernel, all pata as module. Old IDE drivers
are static in the kernel, maybe a conflict there.
Upon pata_qdi my machine crashed in a kernel panic. Here 's what I found
relevant in /var/log/messages

I tried 'modprobe pata_qdi' after reboot and my system just froze, no more
output afterwards to /var/log/messages. Had to hard reset the machine.
The system I tried it on is an out-of-the-box Mandriva 2007.
.config can be supplied on demand.
