Re: Sun4/110 "Panic: Crazy Interrupts"
Hi,

and if we look at the log message for R1.31 of the BW2 driver:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/sun/bwtwo.c?only_with_tag=MAIN
I made a change to only write 32 bits at a time to avoid WRITE,SZERR crashes
on P4 framebuffers. We must be writing more than 32 bits somewhere, maybe
when we initialise the Brooktree DAC. As I wrote in the earlier mail, it
would be good to get the backtrace/line number.

Julian
