Refer to linux/drivers/media/common/saa7146_fops.c:saa7146_buffer_next()
void saa7146_buffer_next(struct saa7146_dev *dev,
struct saa7146_dmaqueue *q, int vbi)
{
struct saa7146_buf *buf,*next = NULL;
BUG_ON(!q);
DEB_INT(("dev:%p, dmaq:%p, vbi:%d\n", dev, q, vbi));
assert_spin_locked(&dev->slock);
if (!list_empty(&q->queue)) {
/* activate next one from queue */
buf = list_entry(q->queue.next,struct
saa7146_buf,vb.queue);
list_del(&buf->vb.queue);
if (!list_empty(&q->queue))
[...]
The code bytes from the above disassemble to:
37: e8 9d 0e 01 c9 call 0xc9010ed9
3c: 83 c4 1c add $0x1c,%esp
3f: 8b 43 44 mov 0x44(%ebx),%eax
42: 89 c2 mov %eax,%edx
44: c1 fa 08 sar $0x8,%edx
47: 38 c2 cmp %al,%dl
49: 75 04 jne 0x4f
4b: 0f 0b ud2a <---+ End of BUG_ON() in
4d: eb fe jmp 0x4d <---| assert_spin_locked()
4f: 8b 77 08 mov 0x8(%edi),%esi ; %esi = q->queue->head
52: 8d 47 08 lea 0x8(%edi),%eax ; %eax =
q->queue->head->next
55: 39 c6 cmp %eax,%esi ; if
(!list_empty(&q->queue))
57: 74 6b je 0xc4 ; skip to else clause
59: 83 ee 2c sub $0x2c,%esi ; buf =
list_entry(q->queue.next,struct saa7146_buf,vb.queue);
5c: 31 ed xor %ebp,%ebp
5e: 8b 4e 2c mov 0x2c(%esi),%ecx <--- Oops here; %ecx =
buf->vb.queue->next
61: 8b 56 30 mov 0x30(%esi),%edx
64: 89 51 04 mov %edx,0x4(%ecx)
67: 89 0a mov %ecx,(%edx)
69: c7 46 2c 00 01 10 00 movl $0x100100,0x2c(%esi)
The Oops happens because q->queue.next is NULL, which is invalid. There
is some sort of saa7146_dmaqueue list or videobuf list corruption
problem somewhere.
I am not familiar enough with the saa7146 nor videobuf to be of much
more help.

Andy
