Hi,
I have a Vaio C1MZX and in the lspci I saw this line:
0000:00:11.0 Non-VGA unclassified device: ALi Corporation M7101 Power
Management Controller [PMU]
So, I assumed it was a watchdog and I compiled with the option:
CONFIG_ALIM7101_WDT=m
But, when I do: modprobe alim7101_wdt
I get the following error message:
Jan 30 00:58:21 hermes vmunix: alim7101_wdt: Steve Hill
<[email protected]>.
Jan 30 00:58:21 hermes vmunix: alim7101_wdt: ALi 1543 South-Bridge does
not have the correct revision number (???1001?) - WDT
not set
What did I do wrong ?
If some patches need to be tried out, I volunteer. :)
Thanks in advance for you reply

You used the wrong South Bridge revision. Seriously, older revisions of
M7101 did not have a WDT. You seem to have an older revision. Sorry.

FWIW, some of the old cobalt boxes had the old south bridge revision
with a WDT. It managed to do resets/wdt off gpio pin 5 though, and
there is a patch in Alan's 2.6.10-ac tree that handles it.
Whether or not it will work with your vaio? Probably not, though I
guess it wouldn't hurt to try (modprobe alim7101_wdt use_gpio=1).

The old Cobalts also had a PIC attached to act as a WDT. :)
