On friday, my 0827 -current kernel died with a panic: bad dir, and
I let it do sync, which failed (syncing disks... 1 1 1 1 1 1 1 [etc]),
after which it said that it was doing a kernel dump, and then rebooted.
Afterwards, the superblock on the root partition was gone, and after I
got the system booted from another disk, most of the root partition turned
out to be screwed, and some damage to the bigger home partition according
to fsck. I re-mkfs'ed the root partition because it was causing panics
even after fsck said there was nothing wrong with it, and after I got
things reinstalled onto it, the system had developed the following problems:
- both login and su don't prompt for password. After entering a username
for an account with a password at the login:-prompt, it just says 'Login
incorrect' without a password-prompt. su just says 'Sorry'. I've replaced
my libs, my login binary, my su binary, my getty, my init, my gettytab
and rebuilt the password dbs and tried a few kernels, but to no avail,
the same thing still happens. I'm on console, neither getpwuid() nor
getpass() had any problems in test programs. The terminal type is set
- serial ports don't work anymore. When I boot to single-user, they work
for some time, but then they suddenly stop (before ttyflags is ran, the
modem has its rts/cts lights on while booting and in single-user. They
also turn off). Trying to cu -l /dev/tty00 -s 9600 says 'Connected',
but nothing is getting to the modem, and exiting cu gets it stuck in
'exiting' state in ttyout.
This is NetBSD/mac68k, and before the crash I had it setup pretty much
similarly, and I'd never seen these problems. The same kernel had been
running most of the time since 0827.
(I sent a mail to port-mac68k on friday, but it looks like the
weekend-long network outage got it)
