Is Intel aware of that problem? Should I bisect it?

I haven't seen it, but 4965 ... we can't really test that on an ongoing basis any more... I'd guess dbbf1755b09eef8ff6dd21c8dafe1606f051ce12 is the problem, seems the only recent thing that actually changed 4965.

Yes, it is dbbf1755, after revert that commit microcode error disappears.

Can you revert only the iwl-4965.c bit of it and try that?
