I have the same problem with the dell inspiron 2650. With the 2.6.27 kernel the next line is:
[ 0.762725] pci 0000:02:04.0: power state changed by ACPI to D0. Now it just stops and I can only press the power button. With the 2.6.28 kernel and pci=noacpi option the next line is: [ 1.111966] pci 0000:02:04.0: found PCI INT A -> IRQ 10 I did some testing: booting with the "acpi=off" kernel parameter -> normal boot booting with "acpi=ht" kernel parameter -> normal boot booting with "pci=noacpi" kernel parameter -> normal boot booting with "acpi=noirq" kernel parameter -> same boot problem booting with "pnpacpi=off" kernel parameter -> same boot problem booting with "noapic" kernel parameter -> same boot problem booting with "nolapic" kernel parameter -> same boot problem The bios (A13) is up to date and gives no options concerning ACPI. ** Attachment added: "apcidump_2.6.27-11-generic.txt" http://launchpadlibrarian.net/26481251/apcidump_2.6.27-11-generic.txt -- kernel 2.6.28 doesn't boot on a dell inspiron 2650 https://bugs.launchpad.net/bugs/327499 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
