| |
as i understand it, schedule_timeout() should always be called with a current->state of TASK_INTERRUPTIBLE or TASK_UNINTERRUPTIBLE, no? based on a trivial check i added to kernel/timer.c, i can read this in /var/log/messages:
... Jul 7 14:48:40 localhost kernel: Bad schedule_timeout state: 0 from Xorg, c015eeb9 Jul 7 14:49:05 localhost kernel: Bad schedule_timeout state: 0 from gnome-terminal, c015ea47 Jul 7 14:50:19 localhost kernel: Bad schedule_timeout state: 0 from Xorg, c015eeb9 Jul 7 14:50:50 localhost kernel: Bad schedule_timeout state: 0 from Xorg, c015eeb9 ...
those last values are __builtin_return_address(0), and here's the snippet from /proc/kallsyms:
... c015e7f2 T do_sys_poll c015eb19 T sys_poll c015eb50 T do_select c015ef10 t core_sys_select ...
i'm guessing those addresses correspond to the calls to schedule_timeout() in do_sys_poll() and do_select(), if anyone thinks it's worth looking at.
