Description Simone Marchioni 2008-04-22 09:07:40 EDT
Description of problem:
When I boot with Fedora 9 Preview i686 Live on a Acer Travelmate 8003LMi it
gives the following error:

ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
ata2: ACPI event

How reproducible:

Steps to Reproduce:
1. Insert the Live CD in a Travelmate 8003LMi
2. Boot from the Live CD
Actual results:
After the message the boot process continues, and the system seems to function
correctly, except for a random notify in the lower right corner about a kernel

Expected results:
A clean boot without the error message

Additional info:
Tried the same Live CD on a desktop PC and a HP laptop and it worked flawlessly.
Comment 1 Chuck Ebbert 2008-04-22 15:53:51 EDT
Can you upload the file /var/log/dmesg from booting the live CD? You'll have to
copy it to permanent storage while the live CD is running, like to a flash drive
or something.

Tried to add the kernel parameter acpi=off and the message disappeared, but
missing ACPI break several things (gnome-power-manager, ecc...)
Comment 5 Bug Zapper 2008-05-14 05:56:29 EDT
