dmesg.old
In your dmesg.old I notice lines like this "usb usb4: Manufacturer: Linux 2.6.32-0.56.rc8.git1.fc13.i686.PAE uhci_hcd"; the version you reported is different. Please paste a uname -a and tell us the reasons why you needed to disable ACPI [from BIOS or as kernel parameter?] in the 1st place. 2.6.32-0.56.rc8.git1.fc13.i686.PAE <- This is the right one, sorry! The reason is that i can work with fedora-rawhide and that it is no more so terribly slow. Let me get this straight : your system works as expected with ACPI disabled, right? Yes, exactly the same thing as in https://bugzilla.redhat.com/show_bug.cgi?id=529840, except that it boot faster. Do you have another kernel at hand to use until an update is available? Yes i have. Thx! Just want to say that the problem still persists in kernel-PAE-2.6.32-0.65.rc8.git5.fc13.i686. The problem still persists in kernel-PAE-2.6.32-7.fc13.i686. Now it also happens with kernel-PAE-2.6.31.5-127.fc12.i686 with todays update. I have to boot with "acpi=off" with all kernels. So what is the clue? The only clue I have in mind right now is a BIOS setting that might cause this. (In reply to comment #11) > The only clue I have in mind right now is a BIOS setting that might cause this. This can't be, because the kernel-PAE-2.6.31.5-127.fc12.i686 was working before today's update, and i wasn't in the BIOS. And kernel kernel-PAE-2.6.31.5-127.fc12.i686 is the only one that works at the time. kernel-PAE-2.6.32-7.fc13.i686 works not once with acpi=off. I switched back to F12-Final because i have work to do and cannot wait that long for bug fixes and F12 has not this bug. I will report back in F13-Preview if that bug further exists. Ok, Fedora 13 Alpha is here and the bug resists. What will be the next steps? kernel-PAE-2.6.33-1.fc13.i686 With ACPI enabled, could you please run grep -r . /proc/acpi and attach the output, along with cat /proc/interrupts; sleep 1; cat /proc/interrupts ?

as your wish..
Could you attach dmesg for this kernel, again with ACPI enabled? It looks like there's an interrupt issue with your USB devices. Also, can you try booting with the following options (one at a time): pci=noacpi noapic (note that the latter is noapic, not noacpi) Created attachment 398854 [details]
dmesg, normal boot
pci=noacpi; makes no difference, the system is also slow noapic; seems to make the system running fast Awesome. Can you provide dmesg with and without noapic, along with /proc/interrupts for both? Created attachment 398880 [details]
normal boot

booting with noapic
Strange, i made a new installation of 13 Alpha and now the system seems to running normal. Maybe i have switched some USB-Devices? The tardiness comes back afer some hours or days, hmm...? I have not seen this bug anymore. Closing.. |
