I tested the latest mainline kernel and can confirm that, the bug still exists
on the folloswing mainline kernel:
Linux 3.8.0-999-generic #201212310405
I have used this kernel also after disabling proprietary Wireless lan
driver. But that didn't help avoid the crash either.
Nevertheless, I found a workaround for this issue:
Setting the following boot option solves the crash problem:
pcie_aspm=off
The above boot option can be easily set by editing /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"
And then running "update grub" command.
Thanks.
