Big problems with 7.1 locking up :-(

I'm pretty certian of that - I hav just been changing kernel config
files, I havent actually csup'd at all.

OK. I think I need at leats 4 kernels to try here: GENERIC (which should
show the problenm), my original DEBUG (which also shows the problem) plus
both of those with BREAK_TO_DEBUGGER included to see if that fixes it. Can
I just add BREAK_TO_DEBUGGER on its own to a config file ? I was wondering
if I need to include one of the other debugger options so that it has
something to break to ?

I was thinking that too - I've been guilty of this in the past too, lumping
my problem in with others under the asusmption that it's all the same. This
is onbiously pretty rare - out of 24 of the HP servers the problems only crops
up on 4 of them. But there is nothing dfferent about those 4.

I will let you know what my various kerenl compiles give me - am buolding
again from scratch, which is slow with WITNESS enabled.
