Hi,
I'm seeing an NMI Watchdog detected LOCKUP go away when I revert this patch previously added into test8.
Any help appreciated. Martin

I hand copied the data from the console, what else is interesting/necessary?
First notices after booting into test8 and the system went silent when starting X, since /home is NFS mounted go generate network and IDE activity.
Reproducible by doing all 3 of these (any 2 and the system stays alive, longer than I want to wait)
1. ping flood A->B 2. ping flood B->A 3. find and grep for garbage from IDE on B's /dev/md/X filesystem
System B is SMP dual Celeron 466Mhz.
