I have this same problem, but it is with IRQ5, 4, 3 and 1. I had to use "noapic" and it seems it worked, but now suspend doesn't work and I can't check the battery charge.
Lucid 10.04RC1 I don't have a dmesg because IRQ1 is the harddrive controller so it doesn't let write a log with the error, but it is pretty much the same as this bug. The dmesg I'm sending is the one when it boots with noapic ** Attachment added: "lspci.txt" http://launchpadlibrarian.net/45446501/lspci.txt -- irq 20: nobody cared (try booting with the "irqpoll" option) https://bugs.launchpad.net/bugs/545339 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
