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)

esp 0x2efae4
ebp 0x2efae4
esi 0x1
edi 0x104af650
eip 0x101cd7
efl 0x10206
If I run addr2line on the gnumach kernel, I get:
[EMAIL PROTECTED]:/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.
