Something has changed with the 2.6 series of kernels that is giving me 
grief.  I suspect there has been some changes to the IRQ code in the 
newer kernel versions that is causing most of the issues I'm having.  
Booting 2.6.14-rc2 results in this message:

Disabling IRQ #15

Booting with irqpoll does work and the system comes up.  If I don't boot 
with irqpoll it will boot but the moment I try and load the ide-cd 
module I get time outs and cmd failed type stuff.  Note that even with 
irqpoll enabled I do see the message only the cdrom now works.  I've 
updated the bios to the latest one on the IBM website in the hopes it 
was a problem with their ACPI code.  I'll attach my full dmesg at the 
bottom of this message. 

Another problem is sleeping.  The machine happily goes to sleep but 
fails to wake up.  Since I don't use sleep very much because of the high 
battery drain I'm okay with this for now.  I'm thinking of investing 
some time into the "hard freeze" patches for suspend to disk stuff but 
haven't decided yet.

I'm hesitant to post to the LKML quite yet in case someone has 
encountered the same problem.

Any thoughts?
Thanks,
Justin Burket
