Status: Incomplete => Fix Released
** Description changed:
Ubuntu 12.04.1 LTS
The issue has something to do with snd_hda_intel because every time this
happens the panic occurs in that module. I use Lenovo Y460 which is known to
have DSDT problems as well.
When running low on battery power or after plugging the adapter, enabling the
hardware rfkill switch is most likely to produce panic on my system.
This bug can be related to another one I experience frequently: after the
laptop has been turned off or suspended on AC power, it cannot start up from
battery normally. It is very similar to
