actually this was the first time that I tried a "normal" kernel.
I haven't chosen to run -mm because it fixed something for me
originally, I just run -mm for a matter of taste ;)

My first thought was it had something to do with pata_via, as
mkinitrd complained it cannot find that module in 2.6.16.9
when I installed it. Taking a closer look, it doesn't even seem
like pata_via is really used, its use count in lsmod output is 0.
But, in the last few releases of -mm I had problems every now and
then where my box didn't want to boot complaining about lost
interrupts on hdb (hdb here, not hda) or it just froze after some
days of uptime (I was able to do sysrq though). Later on I ran
SMART self tests on both my hard drives which didn't reveal any
errors. Google told me some other guys with VIA based boards had
similar problems which went away when using a board with another
vendor's chipset. Being a lazy bastard and having no real time I
stopped digging into this...
How to debug? I might try unapplying VIA and/or IDE related patches
from -mm until I get the same problem like with the stable series.
If one would tell me which patches I should try :-)
Here's the dmesg output concerning my IDE controller:
