2.6.13.2 crash on shutdown on SMP machine

[Clemens Koller <clemens.koller@anagramm.de>]

Hi!

Last night, right before thinking about going to bed, my newly
installed old SMP machine crashed after a #shutdown -h now
as shown below:

linux-2.6.13.2
old Tyan Tomcat Board, Dual Processor, 2xPentium MMX 200MHz
SMP enabled, preemption enabled..

[...]
Shutdown: hda
Power down.
Badness in send_IPI_mask_bitmask at arch/i386/kernel/smp.c:168
c010fdd5    send_IPI_mask_bitmask+0x65/0x70
c0110236    smp_send_reschedule+0x16/0x20
c01188d6    __migrate_task+0xb6/0xc0
c01189ad    migration_thread+0xcd/0x120
c01188e0    migration_thread+0x0/0x120
c012ef43    kthread+0x93/0xc0
c012eeb0    kthread+0x0/0x120
c010104d    kernel_thread_helper+0x5/0x18

The board cannot do any acpi and auto-powerdown thing.
It should just stop after "Power down."

I can try the latest git or 2.6.14-rc2 tonight and get you
some more info (.config) when I am back home...
BTW what is IPI? Any ideas? What do you need to track down
this issue?

Thanks,
