Hi!

Can you please post more details.
What exactly causes the crash?
phpsysinfo does a lot of stuff.
On my test bed it works fine.

Hmm, I did a lot git bisects on UML 2.6.35 to 2.6.36.
2.6.36-rc1 does not always compile. You need no apply f3c072a first.
I've not seen any crashes during bootup nor shutdown. Can you provide some 
more details?

Thanks,
