Comment 4 Jason HU 2007-12-21 09:45:57 EST
Also, the brightness buttons (Fn+F6/F7) of toshiba a135-s2386 still not work
well(/proc/acpi/video/VGA/LCD/brightness works well, but pressing Fn+F6/F7 can
only makes brightness up to the highest level, the gnome-panel brightness applet
can not get laptop brightness). 

I knew there are some bug report about that issue and the new kernel
( do have workaround code in the acpi/ec.c, so I upgraded to the
new kernel, but now it seems that it does not help.

Comment 5 josip 2007-12-25 12:59:33 EST
Possibly related: Kernel royally locks up on reboot, and
prevents BIOS from starting.  The only way to recover is to physically unplug
the machine for about a minute.  On the same machine (Intel D865PERL motherboard
& BIOS), previous kernel reboots normally.  BTW, "acpi=off"
doesn't help, so the trouble with may go beyond ACPI.

Again, works normally but doesn't.
