Description Glenn Matthys 2006-02-15 06:54:13 UTC

Most recent kernel where this bug did not occur: 2.6.11.7
Distribution: CRUX

The computer is a:

Compaq DL 360
Dual P-III 1266 Mhz
512 MB SDRAM PC133 ECC
You can find a full dmesg here:
http://users.opengate.be/~glenn/smpcompaq/dmesg.txt

Upon "halt", after the rc scripts finish, the kernel seems to crash with this
message:
Badness in send_IPI_mask_bitmask at arch/i386/kernel/smp.c:167
Here's a screenshot of this:

This does not happen upon reboot.

If you want more information don't hesitate to contact me.

Could you check if you can start with no_broadcast=1 boot arg and see if it 
repeats itself?

Comment 3 Ashok Raj 2006-02-15 15:40:47 UTC

Looks like this got fixed after 2.6.15...

Could you try this patch instead.

Comment 4 Adrian Bunk 2006-02-27 15:54:57 UTC

This issue should already be fixed.

Please reopen this bug if it's still present in kernel 2.6.16-rc5.

Comment 5 Eric W. Biederman 2006-02-27 23:00:21 UTC

You can remove the -p option to halt to avoid this problem in earlier kernels.
