 Wow, we're up to three Davids now, this might get confusing.  =)
 
 Ok, so here are the answers to David Brownlee's questions b) and c) earlier 
 in the bug report.
 
 b)  Same as before but install via CD-ROM.  I used the 11/20 ATARITT HEAD 
 built kernel.  No networking set up.
 Result: not exactly the same panic but consistent with the "lock error" 
 panic in terms of when it occurred.

 c)  Same as b) but with BOOTX kernel.  No networking set up.
 Result: mostly the same as b)...  Different panic but consistent with the 
 "lock error" panic in terms of when it occurred.

 Sorry about the fuzzyness of the second shot.  Most of it is duplicative 
 with the third shot which is much sharper.
 
 David (Holland), if there's a better place to upload the screenshots so you 
 don't feel compelled to transcribe them, please let me know!  =)
