I take it you mean that you want to stop using toshiba_acpi for the time
being? Simply run 'sudo modprobe -r toshiba_acpi' to remove it for your
current boot, and 'sudo apt-get remove toshiba-acpi-dkms' to remove it
for subsequent boots.

Right, some kind of limit on the number of retries wouldn't be a bad
thing. But in this case even executing that code path is pointless --
your machine doesn't support HCI_SYSTEM_EVENT at all. I think that the
INFO method can be used to read hotkeys, so a better solution is to get
your machine to use that instead.

It's neither right now, just something that your machine supports but
Linux doesn't currently use. If the WMI interface is going to be
commonly supported on Toshibas it may be better to use it than what
toshiba_acpi currently uses.
