Hello,
no, changing to printk(KERN_CRIT "XXX: ...", ...) in kernel/workqueue.c didn't
print anything I could read. Would it appear before the "panic screen"? But I'm
not able to scroll back.
The Panic screen starts with
BUG: Unable to handle kernel NULL pointer dereference at 0000000000000008
IP: [<ffffffff8103eef1>] delayed_work_timer_fn+0x13/0x70
and the Call Trace with
Call Trace:
<IRQ>
[<ffffffff81056fbf>] ? ktime_get+0x5f/0xf0
[<ffffffff810342c6>] ? run_timer_softirq+0x106/0x220
[<ffffffff8105cc44>] ? tick_handle_oneshot_broadcast+0xc4/0xe0
Do I need special settings in the kernel config?
