Long delay in boot sequence to LVM2 striped array

[Simon Rodan]

There is about a 10 second delay in the boot process before this message is generated in the demesg log:

"generic-usb 0003:1778:0204.0005: usb_submit_urb(ctrl) failed"

This is the same bug as 800313 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/800313) but apport-collect wasn't alloing me to add the requested missing log files (even after changing its staus back to New.

The problem only manifests itself when booting from my hard drives (an LVM2 striped array), and not when I boot from the SSD I installed.

Simon Rodan, thank you for reporting this and helping make Ubuntu better. If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

I installed the headers and kernel files for 3.5.0-030500rc7-generic but the boot process stalled.

[penalvch (penalvch)]

Simon Rodan, could you please test for this problem in a Quantal live CD?

[Simon Rodan (simon-rodan)]

The same delay is present in the Quantel live CD (27-Jul-2012 09:43 760M Desktop CD for 64-bit PC (AMD64) computers (standard download)). The demesg log is attached.

[penalvch (penalvch)]

Simon Rodan, did this problem not occur in a version of Ubuntu prior to Precise?

[Simon Rodan (simon-rodan)]

Here (in the next two comments) are the results for 9.04 and 10.04 (the only two back releases I've kept). Neithier exhibits the 10 second wait that 12.04 does.

[Simon Rodan (simon-rodan)]

The dmesg file for 9.04:

[Simon Rodan (simon-rodan)]

The dmesg file for 10.04:

[penalvch (penalvch)]

Simon Rodan, ok. The next step would be to narrow down this kernel versio regression to a particular release. Once this is done, then a kernel commit bisect may occur. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[Simon Rodan (simon-rodan)]

Two updates - first I have tested older versions fo the kenel from disk (rather than from CD as above) and the problem is present in 2.6.33 and 2.6.38. Second, the problem only manifests itself when booting from my hard drives (an LVM2 striped array), and not when I boot from the SSD I installed yesterday.
In the next four posts I am uploading the demesg files:

[Simon Rodan (simon-rodan)]

dmesg for 2.6.33-02063320-generic

[Simon Rodan (simon-rodan)]

dmesg for 2.6.38-15-generic

[Simon Rodan (simon-rodan)]

dmesg 3.2.0-27-generic from disk (LVM striped array)

[Simon Rodan (simon-rodan)]

dmesg 3.2.0-27-generic from SSD

[penalvch (penalvch)]

Simon Rodan, ok. For now, please disregard https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1029546/comments/10 . As well, just to clarify:
+ If you run the Live CD environment of 9.04 and 10.04 this problem does not occur?
+ If you install to disk 9.04 and 10.04 and setup them up in an LVM2 striped array, this problem does occur?
+ If you install to SSD 9.04 and 10.04 this problem does not occur?

[Simon Rodan (simon-rodan)]

So... I'm not really sure what's happening.

I've booted from 9.04 (2.6.28-11) on CD and the problem -- "usb_submit_urb(ctrl) failed" -- is there
It's there too on 10.04 (2.6.32-21) and 12.04 (3.2.0-23) booted from CD. The rason I think I didn't notivce is that other processes were takign longer to complete (/O waits) and so the gap before usb_submit_urb failed is shorter, but the command fails in all cases, irrespective of whether the kernel is on a hard disk, a solid state disk or a CD

 Attached as a file with all the tests I've done

dmesg (dvd) 2.6.28-11-generic_x86_64
dmesg (dvd) 2.6.32-21-generic_x86_64
dmesg (dvd) 3.2.0-23-generic_x86_64
dmesg (ros) 2.6.33-02063320-generic_x86_64.
dmesg (ros) 2.6.38-15-generic_x86_64
dmesg (ros) 3.2.0-27-generic_x86_64
dmesg (ssd) 3.2.0-27-generic_x86_64

Sorry I haven't been much help...

[Simon Rodan (simon-rodan)]

A process of elimination has narrowed down the problem to a webcam - the IPEVO Point 2 View USB Document Camera - which is the cause for of this problem. (The problem seems unrelated to lvm2)

[penalvch (penalvch)]

Simon Rodan, could you please plug in the IPEVO Point 2 View USB Document Camera, unplug all other USB devices, execute the following at a terminal, and post the results to this report:
lsusb

[Simon Rodan (simon-rodan)]

Here's the dmesg log with the Ipevo camera as the only USB attached device.
