Till now I was working with a very stable NetBSD 1.0 and 1.1 system,
However, since I added a 1GB IBM SCSI-disk (sd1), it often panics.
There are 2 other SCSI devices, sd0 and cd0.
I don't have any problems if I do not mount sd1 (the IBM disk),
or if I do nut use it together with the CD-ROM.
But copying a whole CD from cd0 to sd1 is always good for a panic.
It looks as if there is to much speed difference between the CD and
the IBM disk.
Btw: swap is on wd0 and sd0.
Some diagnostic info:
From /var/log/messages

...
/netbsd: sd1(aha0:2:0): timed out
/netbsd: sd0(aha0:1:0): timed out
The console message:
panic: timeout aha0: not taking commands
After reboot: in /var/log/messages :
-----------------------------------
savecore: reboot after panic: should call debugger here (aha1542.c)
savecore: writing core to /var/crash/netbsd.4.core
savecore: writing kernel to /var/crash/netbsd.4
Anyone has some ideas or suggestions what the reason for the
time-outs could be??
