[Bug 10711] BUG: unable to handle kernel paging request - scsi_bus_uevent
http://bugzilla.kernel.org/show_bug.cgi?id=10711
------- Comment #1 from [email protected] 2008-05-20 05:19 ------- Bug happend at least twice on my desktop with 2.6.26-rc3 - thought now I do not have such a backtrace as this deadlock now kills the machine - I just know that RIP was from scsi_bus_uevent. If it would be worth to add - I could try to add a camera snapshost - but the trace is far from complete (just some bottom lines :( ).
The error happens once per couple reboots - but it is unpredicteble and hard to check. But it is definitely present in -rc3

------- Comment #2 from [email protected] 2008-05-20 14:19 ------- Yes I still see it too despite the patches mentioned in
http://groups.google.com/group/fa.linux.kernel/browse_frm/thread/b64dbe94dea882cb/a8f1d83328fcbdc3?#a8f1d83328fcbdc3
. I bisected it down in
http://groups.google.com/group/fa.linux.kernel/msg/c36e78f19fc4aaa3 and reverting the commit [dc16f5f2ede8cc2acf8ac22857a7fecf3a4296c2] PNP: make generic pnp_add_dma_resource() semmed to make the problem go away.

------- Comment #3 from [email protected] 2008-05-23 12:45 ------- This seems to have been resolved by James's patch in

------- Comment #4 from [email protected] 2008-05-23 14:25 ------- Is this the bugfix - or just the patch hides the real problem ? I would have assumed that scsi_bus_uevent should not have been called at all for the non-scsi device

------- Comment #5 from [email protected] 2008-05-24 03:26 ------- Many subsystems (like the new PATA/SATA layer and USB block devices) also utilise the SCSI layer.

------- Comment #8 from [email protected] 2008-06-02 06:15 ------- I'll had to make more test boots to see if the bug is still present - but I do not have a good testcase where I could easily replicate the bug - it happens randomly during the boot - I think no patch solving this issue was committed to the mainline so far ?

Hi
I've not see this bug over quite a few recent reboots - so I'd would have considered this bug also fixed for me - if the problem reapers I'll reopen this bug.
(Well if there was no commit fixing this bug directly - it's hard to be sure the bug is fixed)

------- Comment #10 from [email protected] 2008-06-16 14:49 ------- There WAS a commit fixing this bug directly - it was carried in the SCSI fixes tree and was commit [1f42ea7bc0ddfadebd9e1c5362b41b53902dbcb1] and started turned up first in the next-20080526 tree and was committed to v2.6.26-rc5 (if gitk is right).
