I have a report that while stress testing the ppa module using the
following shell script (or equivalent) can cause a system crash.
#!/bin/sh
while(true)
do
insmod ppa
rmmod ppa
done
After killing the klogd I noticed that the scsi host number rolled
over at 128 (went to -128) and started climbing towards 0. If there
was a second scsi adapter other than ppa (internal pci card etc)
would this cause a clash when two hosts shared the same host id?
