WAPBL and IDE mac68k

[John Klos <john%ziaspace.com@localhost>]

Hi,

I've been having a problem with my Quadra 630 system panicing on boot. It 
was hard to figure out what was going on - a netbsd-5 kernel panics, a 
-current kernel boots, but a -current kernel from 31-December-2009 works.

It happens even when I try to boot to single user mode because I see the 
message saying "/: replaying log to memory" right before it panics. Not 
sure why the journaling stuff happens when booting in single user mode 
without mounting any filesystems, but that's what it is.

When I moved the drive to the same machine's SCSI bus, it works fine with 
any kernel, so this is specific to the IDE bus of the Quadra 630-type 
machines.

(1) How does one start up in single user mode WITHOUT filesystems getting 
read?

(2) Who knows enough about WAPBL and IDE busses to guess where to look for 
a possible solution to this problem?

Thanks,
John Klos
