Description Steve 2009-10-20 11:58:56 UTC 
Description of problem:

Since F12-Alpha (now Beta), the system is terribly slow. Booting needs about 30 minutes with a Pentium 4, 3Ghz, 2.5G RAM. And after login in, you cannot work with Gnome. I don't now if this have something to do with HD I/O?


Version-Release number of selected component (if applicable):
kernel-firmware-2.6.31.1-56.fc12.noarch
kernel-PAE-2.6.31.1-56.fc12.i686

How reproducible:
Always

Steps to Reproduce:
1.Boot
2.Wait 15 minutes
3.Log-in
4.Wait 10-15 minutes
5.Try do do something
6.Wait...  

Actual results:
Everything is terribly slow.

Expected results:
System should work normally

Additional info:
I have no idea..
Comment 1 Steve 2009-10-21 10:27:30 UTC 
Setting acpi=off to the kernel parameter does workaround the problem and makes the whole system (with booting) much faster. Please inform me which information you need to fix that problem!
Comment 2 Chuck Ebbert 2009-10-21 22:16:14 UTC 
1. Boot the normal (slow) way
2. Then boot with acpi=off
3. Attach the files /var/log/dmesg.old and /var/log/dmesg (separate plain-text attachments) to the bug report.

dmesg without acpi=off

Seems to be fixed in kernel-PAE-2.6.31.1-56.fc12.i686, the system is booting fast and Gnome also works fine.

Thanks for reporting back.
Comment 7 Steve 2009-11-30 07:47:32 UTC 
Please reopen this bug since kernel-PAE-2.6.32-0.56.rc8.git1.fc13.i686 also boots only with "acpi=off". I just upgraded from F12 to rawhide.
