3.16 scsi worked fine, 3.17-rc1 misbehaves on 3 of my sparc64 test 
machines. E220R and E420R are with onboard 5c3875, V210 is with onboarc 
53c1010 and all behave the same. Any ideas whre to dig deeper? bisection 
might be nontrivial, because of sparc64 changes that are OK on 3.17-rc1 
again - but is possible if nothing else helps.

We've got a parisc with an 875 as a root SCSI bus ... I haven't got
around to building for it yet, but I might find time to try today.

Does it detect drives in the bit you cut?  I ask because one of the
symptoms of a misrouted irq is random problems with bring up.  However,
if anything is detected, then the irq must be OK.

Come to think of it, I have couple parsisc with 875 too, will try.

No, nothing scsi related - rtc detection etc.

Same on parisc:

sym0: <1010-66> rev 0x1 at pci 0000:20:01.0 irq 22
sym0: PA-RISC Firmware, ID 7, Fast-80, LVD, parity checking
sym0: SCSI BUS has been reset.
scsi host0: sym-2.2.3
random: nonblocking pool is initialized

and hangs here. So hopefully it is reproducible for you.

And also independent of the sparc changes.  The only other change in the
window you quote is 64 bit luns.

Bisection (on PA-RISC) points to:

71e75c97f97a9645d25fbf3d8e4165a558f18747 is the first bad commit

I guess you need this fix:

diff --git a/drivers/scsi/scsi_lib.c b/drivers/scsi/scsi_lib.c
index 9c44392..ce62e87 100644
--- a/drivers/scsi/scsi_lib.c
+++ b/drivers/scsi/scsi_lib.c
@@ -1774,7 +1774,7 @@ static void scsi_request_fn(struct request_queue *q)
 	blk_requeue_request(q, req);
 	atomic_dec(&sdev->device_busy);
 out_delay:

+	if (!atomic_read(&sdev->device_busy) && !scsi_device_blocked(sdev))
 		blk_delay_queue(q, SCSI_QUEUE_DELAY);
 }


James already sent it to Linus.

That's fixed upstream:

commit 480cadc2b7e0fa2bbab20141efb547dfe0c3707c
Author: Guenter Roeck <linux@roeck-us.net>
Date:   Sun Aug 10 05:54:25 2014 -0700

    scsi: Fix qemu boot hang problem

Could you try with a kernel that has that fix?

Thanks,

James

Yes, the box boots now fine with the fix.

Yes, works for both sparc64 and parisc.
