FC8 and Toshiba satellite running from batteries wont boot

[Erick Perez]

Hi,
Last night i loaded the latest FC8 on my toshiba satellite l35-sp4068.
it boots fine except for some modules (wifi, toshiba_acpi, etc) but
those problems might be resolved over time.
However what puzzles me is that it runs perfectly when plugged to the AC.
However,
If fc8 is booted and i unplug the AC, it takes over two minutes for
fc8 to "see" that we are now running on batteries.
if i shutdown fc8 then unplug the AC then boot fc8 again, it panics.
kernel starts booting and then panics. it miay be something related to
fc8 not realizing we are running on baterries beacuse if i plug the
laptop again to the AC and boot fc8, it boots perfectly.

some modules do not load.
modprobe toshiba, modprobe toshiba-acpi fail with "device not found".

has anyone experienced fc8 in a laptop where you can boot perfectly
plugged to the ACbut not when running on batteries?
any parameters that can be passed to the kernel at boot?

I have even tried "single" mode at boot, no help.

thanks,

I managed to write some of the dump.

here it is:

***********************
uncompressing linux...Ok, booting the kernel
Red Hast nash version 6.0.19 starting
BUG: unable to handle kernel NULL pointer dereference at virtual
address 00000024
printing eip: c04b93d5 *pde = 77e2c067
modules linked in: sata_sil libata sd_mod scsi_mod ext3 jbd mbcache
uhci_hcd ohci_hcd ehci_hcd

*****************************
then the boot stops. However if I press ctrl-alt-del I get:
md: stopping all devices..

and then my laptop reboots.

toshiba_acpi does only work on some Toshiba laptop. Some models are built 
by Toshiba itself (Toshiba BIOS), some are Compal OEMs (Phoenix BIOS).

toshiba_acpi does work only on machines with a Toshiba BIOS.

For Compal machines you might look into the omnibook kernel modul. This 
driver is not included in Fedora kernel, so you have to compile it by yourself.
