USB Stops Working (Disabling IRQ #19) Gutsy Gibbon Beta

I have a similar bug and I found that disabling Bluetooth fixes this problem. However this bug still needs to be fixed because I need to use bluetooth.

Hi Robbob,

I assume the issue still exists in the final 7.10 Gutsy Gibbon release?

Also, have you tried booting with the "irqpoll" option as suggested in your dmesg output? Thanks.

And one last request :) . . .

The Hardy Heron kernel was recently uploaded for testing. We'd really appreciate it if you could try testing with this newer kernel and verify if this issue still exists. Unfortunately, the Hardy Heron Alpha1 LiveCD was released with the older 2.6.22 kernel. You'll have to manually install the newer Hardy Heron kernel in order to test. This should not be the case for Alpha2 which is set to come out around Dec 20. However, here are the instructions to install if you choose to do so, otherwise just wait for Alpha2 to come out:

1) edit the file /etc/apt/sources.list and add the following line:

deb http://archive.ubuntu.com/ubuntu hardy main restricted

2) sudo apt-get update
3) sudo apt-get install linux-image-2.6.24-1-generic
4) reboot and select the new kernel from the grub menu

After you've tested, please feel free to revert back - ie boot into the old kernel, sudo apt-get remove linux-image-2.6.24-1-generic, and remove the line from /etc/apt/sources.list . Please update this report with your results. Thanks in advance!

This bug is still present in Gutsy kernel 2.6.22-14-generic

Booting with "irqpoll" kernel command line option seems to fix this problem.

upgrading to kernel 2.6.24-1.2 also seems to have fixed the problem

Thanks for the update Ani. Per you last comment that this appears to be fixed against the 2.6.24-1.2 kernel, I'm going to mark this as "Fix Released" for the current development kernel. However, against linux-source-2.6.22 this bug does not meet the criteria for a stable release update and will be closed. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates . Thanks!

It turned out to be a hardware bug which was fixed in the latest BIOS update from Lenovo.

I've just been debugging an identical error on a Toshiba laptop ...

This looks consistent with https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/88746Ze ..? Possible duplicate ?

Alternatively, consistent with https://bugs.launchpad.net/debian/+source/linux-source-2.6.20/+bug/85488 ..? Possible duplicate ?

USB still stops working after random amount of time in gutsy, 2.6.24-2

My mistake USB is fine now.
