Thanks for the info, I have discovered some interesting things recently. I went ahead and reverted to Fedora 9 since I knew that one worked for me and found that the IRQ is being shared by the same 3 devices. I then updated the kernel on Fedora 9 to 2.6.27 (which is also what Fedora 10 starts out with) and got the same IRQ disabled messages and sure enough my computer locked up within a few minutes of booting that kernel. Luckily I still had the 2.6.25 kernel installed, so I booted into that one instead. <br><br>Does this mean there is a possible problem with the 2.6.27 kernel? What is the actual cause of this problem?<br><br>If you do a google search on Linux IRQ Disabled you will find that this problem has existed in various forms without identifying the actual cause. I should mention that I cannot move around my devices (they are either builtin or using the only compatible slot). I also do not have a disable PnP OS option in BIOS. I also saw a suggestion to change the SATA mode to AHCI in BIOS instead of IDE, but I don't have that option either (for me only RAID or non-RAID). This worked from some, but I think in their case the ata device was involved in the interrupt that was being disabled.<br><br>- Curtis George<br><br>> Date: Sun, 4 Jan 2009 21:03:14 +0900<br>> From: debian@herakles.homelinux.org<br>> To: fedora-test-list@redhat.com<br>> Subject: Re: IRQ Conflict<br>> <br>> Mick M. wrote:<br>> ><br>> <br>> >><br>> >> I'm guessing that when I installed Fedora 9 with all<br>> >> the USB unplugged that is chose differet IRQs so there was<br>> >> no confilict (I'm not sure though).
