|Please, try this out:
|In brooktree848.c:bktr_intr, uncomment the following line:
| /* printf(" STATUS %x %x %x \n", s_status, bktr_status, t_pc); */
Interesting. It appears the freeze is related to disk I/O.
When I uncommented to STATUS print, I found that TV would consistently
freeze the system almost instantly after invocation. Only a few fields
make it to the frame buffer. It even froze once in the middle of the
second field.
Experimenting, I found that if I commented out:
*.notice;kern.debug;lpr.info;mail.crit;news.err /var/log/messages
in syslog.conf leaving:
*.err;kern.debug;auth.notice;mail.crit /dev/console
in place then I was back to getting my 1-30 seconds of video before a
freeze.
With this setup, when I quit TV before a freeze occurred, the STATUS
prints appeared on the console after TV was exited (see attached). Also
attached is top of my verbose boot output.
