Ok, noticing there have been a lot of updates in sys/kern etc during
easter, I cvs up'd tonight and rebuilt a complete distribution, put a copy
of the TS7200 epe0 kernel in DESTDIR, MAKEDEV'd its /dev etc and
TFTP-booted the corresponding netbsd-epe0.bin image. Still *boom* with an
Noticed the following interesting tidbits:
With default TS7200 kernel, at:
root on 192.168.1.6:/export/tsarm
/etc/rc.conf is not configured. Multiuser boot aborted.
Enter pathname of shell or RETURN for /bin/sh:
If I press return or type /bin/sh, I get an immediate "locking against
myself" panic as described earlier.
If I type "/bin/ksh" instead... it works.
With an "opions LOCKDEBUG" kernel, I don't seem to get a kernel panic at
all; at least I can configure rc and customize some /etc files with vi,
create a user and set passwords, set time with ntpdate, and boot all the
way to multi-user and run "find /" on the entire fs without problems --
seems to work ok so far. Without it, I get the mutex error panic pretty
much instantly on attempt to start multiuser boot.
The lock the kernel is crashing on (via sys_read ... pipe_read) is:
COMMON 0x00000000c0516d8c 0x118 kern_synch.o
..which seems like a pretty bad thing to happen. :) I'm going to see what
happens if I boot a stock 3.1 release build instead later this week.
Any help on how to proceed from here greatly appreciated.
