I think I've dealt with this oops now, see my recent patches to this

I have them queued to review in depth, although in that specific case I
don't know if I can help - none of my cards set the BIOS provided
value..

Judging on a FREQ value (about 125) from the boot logs, the BIOS had set up PLL to 50 MHz (125/192 ~ 32/50) which should have "spoilt" the value in the f_CNT register. Hence, we may guess that the BIOS had saved the f_CNT value beforehand. If not, there's not much we can do except to guess at the DPLL frequence that BIOS might have set.
