I've updated to the latest -current, and things have gone awry.  At boot, 
the console freezes
at the end of the dmesg.  The startup process continues, tho, and I can 
telnet into the box.  Then madness ensues.  The contents of some files I 
create disappears, top freezes after listing the processes, never showing 
cpu usage, &c.  Switching to the wd drivers fixes everything.  Below is the 
dmesg from the kernel with ATA.  The previous working kernel was compiled 
from Oct. 5 sources.  Just ask for any other info you need.

Thanks,
Greg
