Oops with loop devices on 2.6.9

From: Chris Spiegel

Hi,
While playing around with loop mounts on kernel 2.6.9 I managed to get
a kernel panic. After messing around with it I can reproduce the
problem reliably. The sequence I came up with to cause the problem:

mount -o loop /dev/loop/0 /mnt
mount -o loop /dev/loop/1 /mnt
mount -o loop /dev/loop/2 /mnt
mount /dev/loop/0 /mnt -t ext2

I know the above is silly and contrived.

An example oops is as follows (I copied this down on paper and then
back, so hopefully I made no transcription errors):

Unable to handle kernel paging request at virtual address 98858a6f
printing eip:
c011345a
*pde = 00000000
Oops: 0000 [#1]
SMP
Modules linked in:
CPU 0
EIP 0060:[<c011345a>] Not tainted VLI
EFLAGS 00010083 (2.6.9)
EIP is at do_page_fault+0x99/0x599
eax: c9100000 ebx: 65642f3c ecx: 0000007b edx: f7d4858b
esi: 00000000 edi: c01133c1 ebp: 988589ff esp: c9100108
ds: 007b es: 007b ss: 0068
Unable to handle kernel NULL pointer dereference at virtual address 00000070
printing eip:
c011345a
*pde = 00000000

I ran this through ksymoops, but it just spit it back at me with the
following tacked on:

Warning (Oops_read): Code line not seen, dumping what data is available


>>eax; c9100000 <pg0+8b9f000/3fa9d400>
>>edx; f7d4858b <pg0+377e758b/3fa9d400>
>>edi; c01133c1 <do_page_fault+0/599>
>>esp; c9100108 <pg0+8b9f108/3fa9d400>


1 warning issued. Results may not be reliable.


So I'm not sure if that's useful. I could also get my system to lock up
if I did the above, but without the loop1 and 2 devices. One time it
just froze, no messages. Another time I got:
double fault, gdt at c1408260 [255 bytes]

I'm attaching my kernel config if that's of any help. If you'd like me
to reply to the list, please CC me so I can set the In-Reply-To header
properly.
