Public bug reported:
Hey
I have possibly found a really strange bug with the irqpoll kernel option which
makes my system totally laggy and unusable.
My TV card is not working properly after some time (20h or so) so I'll have to
boot with the "irqpoll" option.
Currently I am running a mainline kernel, but the problem also exists with the
normal, stock kernel from ubuntu 12.04.
I attached the lspci-vnvn.log.
(With lagging I mean that the mouse cursor is totally slow and watching TV in
the XBOX Media Center i.e. XBMC is quite slow)
If you need any more log files, etc. just ask ;)
Thanks in advance.
