Dear all,
using SuSE 9.2 with kernel 2.6.8 (it's 2.6.8-24.14-default in SuSE numbering)
with APM results very often in this series of messages in /var/log/messages.
I am using a thinkpad A31. I would be grateful if someone could at least
explain what the following messages mean. Why is kernel disabling my IRQ #11?
Which device is to blame?
Thank you all in advance,
Mauro
