I don't experience a lock-up, but something even more nasty: corruption. 
I have a IIci which used to run 1.6 netbsd fine and  openbsd 3.3 
perfectly fine. Rock-stable. I then put in the hard-drive of my q610 
which sadly died but which was rock-stable too, I definitvely miss that 
beast!
Anyway, all my attempts to isntall netbsd 2.x or 3.0 (the latest today) 
fail, in a bigger or smaller degree there is soemthing unreliable in the 
scsi handlign. If I ftp and download a tar.gz it might checksum wrongly 
on uncompression ! Once I was able to isntall a semi-usable system and 
beside s noticing some strange RAM waste (but other reported that and it 
may be solved) usage would suffer HD troubles and unreliable files and 
even lock-ups (but I suspect that some binaries uncomrpesed and 
installed wrongly, you can't be sure of anything).

unfortunate ly at the moment I don not have another spare HD and also no 
t the time to parition, format and install both macos and netbsd on it, 
especially since our installer is still broken.
