Weird USB error stalls all other driver loading.

[Alistair Buxton]

First reboot after updating to 2.6.31-15 decided to run fsck on a USB flash drive I had left plugged in. After it eventually loaded up to desktop I noticed a Bluez error window, and then I noticed sound was not working. Unrelated you would think?

Checking dmesg, I saw a lot of errors coming from the disk which had been checked. I also noticed the access light on it was flashing like mad. So I pulled it out. Instantly my USB bluetooth was detected, Bluez loaded, and stranger still, my sound (which is a PCI card) started to work.

Checked dmesg again, and it looks like vbox drivers were also blocked from loading by this.

The line:

[ 426.106612] usb 1-8.1.1: USB disconnect, address 50

in CurrentDmesg.txt is where I pull the bad flash disk. At this point, you can see all the hardware in my machine spring to life :)

About the only thing that worked before this was the display, PS2 keyboard and USB mouse.

Hi Alistair,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 488101

Also, if you could 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 . 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. Please let us know your results.

Thanks in advance.
