Bug Description
During bootup there is an unacceptably long delay. After looking through the dmesg log it turns out that the delay seems to have been at a line that says
[ 149.596033] pci 0000:00:13.5: EHCI: BIOS handoff failed (BIOS bug?) 01010001
I did not notice this problem with Ubuntu 10.10 - it's new since I upgraded. It may be related that in the previous version the fan (and FN+F6/F6 brightness keys) wasn't working on initial bootup. If I did suspend and then resume, the fan and brightness keys worked as they do in Windows. Now in Natty, the fan seems to increase in speed gradually but then when the temperature cools down the fan doesn't slow down. Also in Maverick, hibernate usually worked fine whereas in this version hibernate just seems to do the equivalent of 'lock screen'.
Am new at reporting bugs so please advise on what other logs/attachments I should post.
I tried selecting kernel version 2.6.35-28-generic on on bootup and the long delay went away.
I looked through the dmesg log and found that the same message comes up, but after 2 seconds instead of after 147 seconds. That's much more bearable!
