We are getting frequent crashes on a Sun Blade 1500, Solaris 8,
and the following is the last message before every crash

pcf8584: [ID 318190 kern.warning] WARNING: i2c_0 lost arbitration;
Controller = 0x28a321 addr = 0x5c

What does it mean? faulty hardware?

Most likely if the machine worked before and nothing changed.

However there rings a bell in my mind regarding a I2C interface problem,
but I think it was on a Blade 100. Is it a Red or a Silver?

Is Openboot updated,I think there is a Openboot rev from mid 2005 on the
Red.

If it is a Red it could be the same problem as the Blade 100 since it is
a few years old to, that problem was a temp sensor to the CPU and fixed
if I recall right with a patch of some kind, Openboot or Solaris.

How frequent it the problem and do you have the possibility to try S9 or
S10 as a test to see of it is a Solaris that causes it maybe run a test
during a weekend?

Thanks Michael, it is a red one. I've applied the latest Solaris recommended
patch cluster and will try updating the OB. (No chance to try Sol 9 or 10)

I will also replace the PSU with one that Sun sent us recently as part of a
recall. No idea if it would be related to this error though.

It crashed about 10 times in the past month, twice in the last two days.

HI, if it the same problem I suspect Sun had a HW timing issue that
popped up after some time when component started to age abit and in
certian temperatures.

And remember always only change ONE thing at a time, if you change two
things at the same time, later trying to back them both out will not get
you back
