Public bug reported:
Hello,
I've got a P5B motherboard with a Core 2 Duo E6600 processor running Edgy Eft
AMD64 (with all updates done).
The card has a Realtek RTL 8168/8111 Ethernet Network Adaptater, and I'm using
SATA hard drives on the Intel ICH8 controller (I'm not using the JMicron's
one). I'm using the normal generic kernel 2.6.17-11 (but the bug was already
there with the 2.6.17-10 kernel). The only modification that I've done is
installing the nvidia driver from their website, but I think it is not loaded
when my bug happens.
>From times to times I'm experiencing a Kernel Panic. I've checked my RAM
with memtest without problem. Here is the Kernel output (I've copied a
part of it as I've got no camera, and no log is written to the disk) :
"..." stands for hexadecimal output that I assume being of no interest.
Realtek RTL 8168/8111 Family PCI-E Gigabit Ethernet Network Adaptater
Driver version: 1.02
Release date: 2006/02/23
I/O Base: 0xB800 (I/O port)
IRQ: 177
Then there is the initialisation of the SD drives (I suppose that it is
my hard drives), and then :
skb_over_panic: text: fff... len: -4 put: -4 head: ff... data: ff... tail:
ff... end: ff... dev: eth0
------[cut here]------[please bite here]------
Kernel BUG at net/core/skbuff.c:94
invalid opcode: 0000 [1] SMP
CPU 0
Module linked in: [here lie a long list of module, I suppose it's juste the
default ones as I have not touched to my kernel]]
Pid: 4056, comm: ifconfig Not tainted 2.6.17-11-generic #2
Rip: 0010:[<...>] <...> {skb_over_panic+92}
Then there is the machine state, I'm not sure that it is useful except for the
call trace, I'm listing only the function name and not the hexadecimal adress :
Call trace: <IRQ> {r1000:r1000_interupt+459}
handle_IRQ_event+44 __do_IRQ+188
__do_IRQ+66 ret_from_intr+0 <EOI>
cache_grow+779 kmem_cahce_alloc+131
__alloc_skb+75 r1000:r1000_open+436
dev_open+47 dev_change_flags+104
devinet_ioctl+741 sock_ioctl+540
do_ioctl+47 vfs_ioctl+659
sys_ioctl+108 system_call+126
Code ...
Rip <...> {skb_over_panic+92} RSP <...>
<0> Kernel panic - not syncing: Aiee, killing interrupt handler!
If there is not enough information let me now and i'll try to find a
camera or something.
I've got the impression that the bug appen when the eth0 driver is
loaded before the SD drives, but I'm not sure that it is the real
reason. The interesting point is that when this bug happens, if I just
reboot the computer by pressing the reboot button, the bug re-happens
nearly always. I need to completely shut it down for a while before
rebooting it, in order for the system to boot properly. So I suppose
that it is maybe one of the component (the Ethernet adaptater I suppose)
that is left in an improper state and that is causing the problem.
