[lug] Seeking thoughts on this crash

[Chuck Morrison]

Did you run your test anytime other than the two times mentioned here ?

To be sure, install RH 7.2 again (on a different hard drive if you have 
one to avoid re-installing SuSE again) and run your test again. If it 
works fine there, then maybe some kernel tuning might be in order. If it 
fails under RH 7.2 now, it's hardware.

You didn't have anything else to do this weekend, did you ?
