>Description:

  After downloading the 200408190000 i386 netbsd-GENERIC.gz
and giving it a try on my fileserver machine (only booting
the kernel, userland is still 1.6).

  It crashed after going multiuser, rather late in the process,
after starting ssh, with a page fault.

  A 10 finger backtrace shows:

_bus_dmamap_load(c075a100,0,c4d0a000,2000,0) at netbsd:_bus_dmamap_load+0xf
icp_ccb_map(c0d1000,c0db8000,c4d0a000,2000,2) at netbsd:icp_ccb_map+0x35

  I have not been able to get a crash dump -- it seems to write
it out ok, but savecore does not find it on next boot. I can try
things out on request though and take pictures of the screen.

  Just crashing where 1.6 would do fine sounds like a serious
regression to me.

>How-To-Repeat:

  Boot a 2.0 kernel on a machine with a icp vortex raid controller?
