Hi,
I am having a very peculiar problem and don't know what else to do.
I am running FreeBSD 1.1.5.1 and am having the following problem.
If I stress the SCSI bus ( I'll show how I do that in a minute), the
bus hangs with the SCSI LED stuck on (in most cases).
The command that I use to stress the bus is:
cd /
find . -type f -print -exec cp {} /dev/null \;
This command will run for a while (5-10 minutes) before hanging.
Sometimes it even completes, but if I run the same command again
it hangs.
Hardware:
ASUS SP3 motherboard
NCR 810 SCSI controller (uses intr 9)
2 high speed serial ports
printer port
IDE/floppy controller
Saturn Chipset
32MB RAM
512KB cache
AMD 486DX2/66
3 PCI slots/ 4 ISA slots
DEC DSP3105 Disk Drive (1 Gig)
Toshiba 3401B CDROM Drive
ATI GUP w/ 2MB VRAM (ISA version)
I don't know what to do from this point. How do I debug this from here?
Thanks for any help!
