pcspkr module causes kernel panic and system lockup

[Omri Iluz]

Hello,
Kernel module pcspkr is causing a complete system lockup consistently when the pc speaker is used on a LG LS55 notebook.

removing pcspkr (rmmod pcspkr) or blacklisting the module completely resolves the issue.

Thanks,
Omri

This has been confirmed and fixed on kernel version 2.6.29 by Zoltan Devai.
This Ubunutu bug can be marked as resolved, unless someone wants to keep it open to keep track until 2.6.29 is out.
