system message keeps popping up "disabling IRQ22"
 

An obvious newbie to Linux, still trying to come up on the learning curve...
What is my system trying to tell me here? I keep getting a popup from syslog about disabling irq22. This is an excerpt from syslog from bootup this afternoon. I think the ICH7 referenced here is the Intel HD controller on my MB (Asus P5W DH). The 3 HDs on the intel controller show up in /dev/discs, but the other two HDs on the Jmicron controller on my MB do not. I'm assuming I don't have the proper driver for the Jmicron controller??

Did you even manage to load the kernel? I have the same mobo and event with quite recent one (ie 2.6.21.5 from my Slackware 12 or 2.6.22.1 from kernel.org), it just takes ages to detect the PATA hard drives plugged to the JMicron controler then just hang shortly after. If I compile the JMicron_pata as a module it manages to start but also takes 30 second trying to probe the SATA ports of the ICH7R and don't manage at all to load the two hard drives plugged to the JMicron chip...

The only way I found to make it boot is to disable the JMicron controler in the BIOS. I'm trying different bios settings and boot options but so far, it still doesn't work really.

system message keeps popping up "disabling IRQ22"
 

Hi Mark,

When I got this message, the system was booted and running but I could not see the devices attached to the JMicron controller, not to mention that the optical drives were never detected. I had to install this distro by copying the installation medium to one of the visible HDs. I had nothing but trouble with this installation and mb as I was trying a dual boot with Linux and XP, so I ditched it completely, installed XP exclusively on this mb, and installed Mandriva 2006 on another computer I had.

Thanks for the reply though!

Mike
