I can confirm this is still occurring in Ubuntu 12.04, with my Radeon HD 5450 ( http://www.asus.com/Graphics_Cards/AMD_Series/EAH5450_SILENTDI1GD3LP )
That section in comment #4 below [ 128.690008] [<ffffffffa012125e>] ? KCL_SIGNAL_Notifier+0xe/0x10 [fglrx] looks very similar to the kernel panic error I receive. I was able to verify this by setting GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="" in /etc/default/grub and running sudo update-grub Version info from /var/log/Xorg.0.log [ 12.460] (II) fglrx(0): Kernel Module Version Information: [ 12.460] (II) fglrx(0): Name: fglrx [ 12.460] (II) fglrx(0): Version: 8.96.4 [ 12.460] (II) fglrx(0): Date: Mar 12 2012 [ 12.460] (II) fglrx(0): Desc: ATI FireGL DRM kernel module [ 12.460] (II) fglrx(0): Kernel Module version matches driver.

I had a look at https://wiki.ubuntu.com/Kernel/CrashdumpRecipe and https://wiki.ubuntu.com/Kernel/KernelDebuggingTricks and wasn't able to figure out a method that worked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/750437 Title: fglrx hard lockup on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/750437/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
