could please one of you try to find out where exactly it hangs? When you 
caused a lockup, use alt-sysrq-p (in the context of the locked process) 
or alt-sysrq-t to generate the call trace for the dead process and then 
please collect the symbol names for the EIP and call trace adresses.

You have to enable the sysrq key in your kernel config to let this work.

A list of symbol names including those of the loaded modules you can 
generate using

$ cat /proc/ksyms | sort | less

thanks for your help,

Holger
