All,
We've been trying to track down a nagging regression seen during some
port-disable/enable testing. The problem occurs anywhere from
20 minutes to 120 minutes of testing under very minimal I/O load:

[ 1144.474364] Kernel panic - not syncing: Aiee, killing interrupt handler!
Basically what is happening from the FC side is the initiator executes
a simple dt test:
dt of=/dev/raw/raw1 procs=8 oncerr=abort bs=16k disable=stats limit=2m passes=1000000 pattern=iot dlimit=2048
against a single lun (a very basic Windows target mode driver).
During the test a port-enable, port-disable script is running agains
the switch's port that is connected to the target (this occurs every
sixty seconds (for a disabled duration of 2 seconds). Additionally,
the target itself is set to LOGO (logout) or drop off the topology
every 30 seconds.
This test runs fine up to 2.6.19. Breakage appears to have been introduced in
2.6.20-rc1 (our firmware-engineer noticed the problem in 2.6.20-rc4).
Unfortunately our efforts a basic bisections have been fruitless as according
to git-bisect the bad commit is:

Not sure how much help it is, but while trying to instrument
as-iosched.c, we can see that the failure has a fairly stable
signature:
[15280.813479] as_dispatch_request: ad=ffff810038704da8 ; reads=0 ; writes=1 ; dir=0 ;fifo_list[async]=ffff81003f4071a0 ad-new_batch=0 ad->change_batch=0.
[15280.827032] as_dispatch_request: q=ffff81003fdae050 ; #_reqs=128 ; lmerge=ffff81003f4071a0 ;.
which means:
static int as_dispatch_request(request_queue_t *q, int force)
{
...
const int writes = !list_empty(&ad->fifo_list[REQ_ASYNC]);
'writes' is set, the batch_data_dir has not changed
(ad->batch_data_dir != REQ_SYNC) in the following segment:
...
if (writes) {
dispatch_writes:
BUG_ON(RB_EMPTY_ROOT(&ad->sort_list[REQ_ASYNC]));
if (ad->batch_data_dir == REQ_SYNC) {
ad->changed_batch = 1;
/*
* new_batch might be 1 when the queue runs out of
* reads. A subsequent submission of a write might
* cause a change of batch before the read is finished.
*/
ad->new_batch = 0;
}
ad->batch_data_dir = REQ_ASYNC;
ad->current_write_count = ad->write_batch_count;
ad->write_batch_idled = 0;
rq = ad->next_rq[ad->batch_data_dir];
goto dispatch_request;
}
ad->next_rq[ad->batch_data_dir] is NULL, and is then passed down to
as_move_to_dispatch() where the first dereference of rq:
static void as_move_to_dispatch(struct as_data *ad, struct request *rq)
{
const int data_dir = rq_is_sync(rq);
borks the machine. What's odd (perhaps it's just our rudimentary
understanding of AS) is that there are segments of code where
ad->next_rq[REQ_ASYNC] is checked against NULL (in 'writes' case it is
not).
Anyway, any ideas or hints? Attached is the .config used.
Thanks,
Andrew Vasquez
