Hi, I applied the patch supplied by Len for drivers/acpi/bus.c which
he comments "# Invoke DSDT corruption work-around on all Toshiba
Satellite"
This works for my C650-194. I am running Ubuntu 10.04 with patched
kernel 2.6.36-rc6, and I have battery support etc.
New dmesg attached. If any other output is of interest please let me know.
It contains:
[ 0.014863] TOSHIBA Satellite detected - force copy of DSDT
to local memory
[ 0.021490] ACPI: Forced DSDT copy: length 0x094DE copied
locally, original unmapped
Many thanks! Will this make it into a future stable kernel release?
For those (like me) new to this, I grabbed the 2.6.36-rc2 kernel
source from kernel.org and patched.
Then as root:
make-kpkg kernel_image
dpkg -i linux-image-2.6.36-rc6_2.6.36-rc6-10.00.Custom_i386.deb
update-initramfs -k 2.6.36-rc6 -c
update-grub
Because stock kernels to date have required acpi=ht and I had
specified that in /etc/default/grub as
GRUB_CMDLINE_LINUX_DEFAULT="acpi=ht splash"
I had to remove that for this new kernel before running update-grub
GRUB_CMDLINE_LINUX_DEFAULT="splash"
Cheers, al.
