next in thread | raw e-mail | index | archive | help
Hi everybody,
While working on my ABit BP6/system hang/stray irq7/temperature problems, I
did a BIOS upgrade to the latest revision. The consequence is that now I
get stray irq7's *always* and many many more than before.
Below I've attached a dmesg and my current kernelconfig. Could you please
take a look at it and see if you spot something strange I've overlooked?
See anything that could explain the stray irq7's there?
BTW, I've solved the temperature problems by installing better cooling (cpu
temperature is now 37 degrees Celcius) and I've completely disconnected all
IDE devices physically and disabled both IDE controllers in the BIOS. The
machine is not overclocked and as far as I can tell I did everything by the
book.
Thanks for your time,
Dave Boers.
