Package: gnumach
Version: 20060826.dfsg.1-1
Severity: important

On high network traffic (usually when apt-getting some packages,
uploading things seems to trigger this much less likely), I get
sometimes get a Mach panic and subsequent reboot.

If I trap the panic with gnumach-dbg, I get (transcribed, so maybe
slightly inaccurate):

kernel General Protection tryp, eip 0x101cd7
kernel: General protection (13), code=0
Stopped at 0x101cd7: movl %exc, 0(%eax)
db> trace
0x101cd7(2ee918)
>>>>> Divide error (0) at 0 <<<<<

cs		0x8
ds		0x10

fs		0x1f
gs		0x10
ss		0x10
eax	  	0xffffff10
ecx	  	0x104af000
edx	  	0x104af000

ebp	  	0x2efae4
esi		0x1
edi	  	0x104af650
eip	  	0x101cd7
efl	  	0x10206

If I run addr2line on the gnumach kernel, I get:

buildd@beethoven:/boot$ addr2line -f -e gnumach-dbg 101cd7
ipc_kmsg_enqueue
../ipc/ipc_kmsg.c:83

This happened both on my HP Omnibook 6000 notebook with a Prism2 PCMCIA
WLAN as NIC, and on the buildd with an Intel PCI EtherExpress Pro100.

This currently makes the buildd reboot/hang every couple of hours.  I
had one person apparently being able to reproduce this with vmware:

18:07 < gijzelaar> currently I use vmware, but I had the same problems
	on a real machine
18:16 < gijzelaar> yessssssssss crash
18:16 < gijzelaar> Stopped at 0x101cd7

but nobody else seems to suffer from this yet.  If you can reproduce
this, please follow-up to this bug report.

If anybody can tell me what else I could do to track this down, I'd be
happy to do that.


Michael
