No crash when idle so far, but it did blow up quite spectacularly after I did the following: 1. Booted 12.04 beta from USB stick 2. Installed lirc, configured lirc for generic Windows Media remote with no transmitter 3. Unplugged IR dongle Unfortunately, I was not able to record the error messag

Hmm...looks like testing on the E-350 machine is currently a no-go. The version of XBMC I have on there depends on FGLRX, and since it's what uses the IR dongle, I'm not sure the problem will happen without it running. Besides, I don't want to go to the trouble of removing FGLRX (I seriously doub

I think this is related to AMD hardware. I just got a new AMD E-350 machine, which has had some mysterious crashes with the 3.0.0-16-generic x86_64 kernel. After disconnecting the IR dongle, it has gone nearly 24 hours without a crash. Annoyingly, I haven't been able to get a proper backtrace be

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested

Yep, it looks like the USB IR remote control device is to blame. I just confirmed that no file or directory called rc0 exists in /sys until I plug in the USB IR device. I got the same kernel oops immediately upon unplugging the device. -- You received this bug notification because you are a mem

Judging by the presence of "usb" and "rc", I suspect my USB remote control device may be to blame. I will do a bit more investigation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/891890 Title: Ke
