Hello,
I installed 2.6.15-rc6-git3 on my ia64 test system and the system hung during
startup. There were "recursion depth exceeded" messages.
The fabric was coming online at the time of hba startup and the targets
hadn't yet been discovered by the switch. Consequently, the hbas saw
loop up but no targets, then the switch generates a state change notification
and the driver for the hbas discovers the targets in parallel.
So, there appears to be another recursion issue with the new fc transport.
I then try rebooting the system again. Discovery happens as expected
at the time the driver initializes each card. Then the system takes an
OOPS.
It's possible the OOPS is related to the qla2xxx serialization issue I reported
earlier.

I tried a third time and got the same OOPS. Repeatable.

I believe I had posted a patch earlier which attempted to address
this:

at least we could get rid of this soft-lockup noise.

It may be related, but, I'm trying to track down a very repepeatable

[SCSI] fix scsi_reap_target() device_del from atomic context
scsi_reap_target() was desgined to be called from any context.
However it must do a device_del() of the target device, which may only
be called from user context. Thus we have to reimplement
scsi_reap_target() via a workqueue.

As for initial testing w/git3, it's hanging during boot.
I'll try and compile KDB into the kernel to get more info.
Perhaps I can do some more work on this over the weekend.
It would seem as though the driver is thrashing the add/delete
mechanism. With lots of host ports and lots of targets, every SCN that
comes in when another host port joins the fabric causes the others
to delete and re-add their targets.
Picture 64 host ports and 128 targets on each. (I only wish this were
my test config. Maybe Santa will bring me some more fabric!)
Perhaps check to see if target is missing after SCN and just
delete it?
As a sanity check, I verified that the system boots properly
with 2.6.14.3.

FYI - you would not see the recursion issue with the lpfc driver. This is a
combination of the qla2xxx driver and the fc transport both using work queue
entries on add/delete. The lpfc driver uses a background thread rather than
work queue entries.
I'll see if there's something similar to what I did before that could be
applied. Otherwise, we'll have to change either the calling rules or the api.
This is one of those things where the micro view looked simple and
straight-forward, but the macro view is showing the inefficiencies of
black-box design.

There's only one path where the qla2xxx driver adds fcports from an
interrupt context and subsequently schedules rport additions, the
RSCN handling in qla_rscn.c. Typically, additions would occur from a
process context via the DPC thread.
Mike, here's a slight variant on the previous patch which will
hopefully handle the locking issues seen above and (temporarily, given
the semantics of rport additions) disables RSCN handling via the
driver's state-machine.
