Comment 9 for bug 30272

Interesting. toshset seems to be asking the kernel for something that fails.

Can you run:
$ lsmod | grep toshiba
for me and paste the output in your reply?

It should list:
toshiba
toshiba_acpi

If one of those is missing, try:
$ sudo modprobe toshiba 2>&1 | tee /tmp/modprobe.log
$ sudo modprobe toshiba_acpi 2>&1 | tee -a /tmp/modprobe.log

And attach /tmp/modprobe.log to this bug.

Thanks for your help.
