[Bug 624701] Re: BUG: unable to handle kernel NULL pointer dereference at (null)

[Brian Rogers]

** Description changed:

- Something like half the time when my system starts, I get an oops in
- dmesg, which appears to be related to the IR receiver in my TV tuner.
- This problem didn't happen in Lucid's 2.6.32 kernel. So far I haven't
- witnessed any harmful effects.

- I just got a second oops after something crashed X and made it restart,
- so I suspect the error is being triggered by X. That would explain why
- the error occurs about ten seconds after the driver is done loading.
- 
- To reproduce the error, I just have to reboot my system until it
- happens. My TV tuner is saa7134-based, and called "MSI TVAnywhere Plus."
+ It crashes whenever the LIRC daemon loads. To reproduce the error, I
+ just have to reboot my system. My TV tuner is saa7134-based, and is
+ called "MSI TVAnywhere Plus."
