Last old PowerMac G5 that I have access to may be starting to fail: iichb0: I2C error

[Mark Millard]

The 2-socket/1-core-each PowerMac G5 has had several
sudden crashes recently, mostly while idle, usually
with no messages. No response but to power controls
once it fails.

But I got one example (so far) where it reported
something as it failed (and the fans then started
to speed up):

iichb0: I2C error

The message was even recorded in /var/log/messages .

The kernel and world have not been updated since
back around 2021-Mar-12 or so. So the behavior
appears to be new, without a system software change
in a similar time frame.
