Message-ID: <1031159814.23852.21.camel@plars.austin.ibm.com> (raw)
In-Reply-To: <3D75CD24.AF9B769B@zip.com.au>
I havn't tried this with stock 2.5.33 or 2.5.33-mm2 yet, but I was
trying the old fork07 ltp test and got a problem when I was testing
mm1. The fork bomb part of that test is now in the fork12 test in LTP
and is not run by runalltests anymore due to the recent kernel changes.
Here's the ksymoops output for now, and I'll see about trying to
reproduce it.
Thanks,
Paul Larson
