The system locks up with either a NULL dereference or an unhandable paging request. The stack trace shows this: paging request NULL dereference _raw_spin_trylock+12 _raw_spin_trylock+20 __spin_lock+22 main_timer_handler+22 timer_interrupt+18 handle_IRQ_event+41 __do_IRQ+156 do_IRQ+51 default_idle+0 _spin_unlock_irq+43 thread_return+187 generic_unplug_device+0 default_idle+45 dev_idle+95 (I can't read the func clearly in this handwriting) start_secondary+1129 I'm guessing this is the same problem only that it once manifests itself as one and another time as the other. The problem is in the call to write_seqlock(&xtime_lock) from main_timer_handler(). I've not been able to determine what patch has caused this to happen, but it is between 2.6.17-rc3 and -rc4. I'm bisecting, but if anybody has a good candidate, it'd probably be faster than doing a complete bisect. cmn --=20 Carlos Mart=C3=ADn Nieto | http://www.cmartin.tk Hobbyist programmer | --=-pyKEBD231fw/xxV1ugpc Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) iD8DBQBEc1RiEVXxXOiy6a4RAo15AKCDN9SG+eCo3vAeYZlbtSq5dMtuZQCgmqzQ qidt2ZgzMvGDdgswmACVrSg= =GkOM -----END PGP SIGNATURE----- --=-pyKEBD231fw/xxV1ugpc-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
