i have spinlock debugging enabled - but indeed the trace could be incorrect, let me re-check it.
doh, wrong script called ... the right backtrace is:
>>EIP; c0106c57 <__write_lock_failed+7/20> <===== Trace; c0120316 <.text.lock.exit+119/133> Trace; c01088c8 <common_interrupt+18/20> Trace; c011ef16 <exit_notify+16/230> Trace; c011f41a <do_exit+2ea/370> Trace; c0125755 <schedule_timeout+b5/c0> Trace; c0126686 <sig_exit+36/40> Trace; c0127c54 <get_signal_to_deliver+2d4/360> Trace; c0107cf3 <do_signal+c3/100> Trace; c012d572 <sys_futex+182/1b0> Trace; c0107fce <work_notifysig+13/15>
(we definitely need kksymoops in the 2.5 kernel - it's just *so* much easier to debug various crashes with kksymoops enabled - especially when debugging over a serial line.)
and this lockup definitely looks related to the signal changes.
