Doh, I searched for the wrong keywords in the archive :-)

Yes, that's the same bug and if I get Dave's mail right he is seeing
the bug on the X4500 and X4200. If it's a X4200M2, it has the same
firmware as the X4100M2, and for this one the bug is not fixed in
the recent update.

Of course I could, but I agree with you that it wouldn't be a good thing.
I can work without the daemon of course and use cron and a endless 
while-loop to reset the timer, and I guess that's better than patching
around such an obvious bug. 
I succeeded in triggering the bug without the bmc-watchdog by just 
accessing the watchdog remotely via "ipmi <machine> ...  mc watchdog 
Thus, Sun has no chance argueing it is some Linux problem with freeipmi etc.
And since we still have support for the X4100M2 I will demand a firmware 
upgrade. Let's see what they do.

I just wanted to make sure there was an obvious workaround that I missed :-)
Thanks! And I will let you know what comes out of the Sun support request!
