I compiled a test server, and got several errors. On bootup, I saw two
messages about keyboard time out. There was a message about a lost
interrupt, and the ncr8xx driver kept resetting.
The system is an IBM 365 PPro, with an IDE cd-rom, an ncr 815 based scsi
card and Dec 10/100 network card. I have two scsi HD's an old 600 meg scsi
1 and a newer 4 gig scsi2. This system works fine with 2.0.x, and would
boot with kernals prior to 2.1.119. I'm currently recompileing the kernel
with the ncr7,8xx driver to see if this will at least let me finish the
bootup.
It appears that I can no longer run a SMP kernel on my UP machine. This
used to be possible, in fact it ran with no problem. Recompileing with SMP
commented out results in a bootable kernel.
