Hmm, perhaps it is not as easy as I thought. On exactly this machine
with exactly this kernel (3.10.11 vanilla with your patch from this
thread), some minutes ago another one came up. The system should have
been mostly idle at that moment. Dmesg appended ... do you need
anything else to have an educated guess? I waited 10 minutes after
the stall message (following your earlier advise), but no further
dmesg lines appeared after that.
Best greetings,
Jochen.
