Subject: [Xen-devel] Another dom0 crash (Unable to handle kernel NULLpointer dereference)

This time running Xen 3.0.2-2, PAE

Please can you supply more information e.g. how many VMs were running,
do you know what they were doing, can you repro, details about the h/w,
amount of memory etc. This is a separate issue from the previous one.
I seem to recall a similar crash has been reported before, but there was
no repro information in the report either.

Thanks,
Ian

There were roughly 40 VMs running on the machine. Host server is a SuperMicro AS-1020A-T, 16G RAM (only 14 shows in Xen :( ), 3ware 9550SX-4LP h/w raid card.

I don't have an easy way to reproduce this. It seems to have happened this time and last when I asked a few of the VM runners to exec hdparm -t.
