Hmm, I think I'll have to repeat that here on the new dualcore I have now.


Other interesting boot messages before the panic are:

		:

  ad2: setting UDMA100 on M5229 chip

  acd0: WARNING - DEVICE_RESET taskqueue timeout - completing request directly
  spin_lock: 0xc240ba6c, indefinite wait!
  spin_lock: 0xc240ba6c, indefinite wait!

I suspect I'm not dropping a lock somewhere; I'll investigate tomorrow.


nata* drivers are compiled in an SMP kernel, running on Athlon64X2
with ASRock 939Dual-SATA2 .  If I yank off the DVD-ROM drive from the
system, it proceeds to mount root fs, then failed:

  Mounting root from ufs:/dev/ad0s1h
  no such device 'ad'

Not sure why this is happening; I use the same major as the old code, and afaict the same minors as well. It works when not doing a rootmount, I'll have to see what game the delayed attach intrhook is playing here.


Although this mother board has a SATA port, the IDE drives are PATA one
and connected to the PATA ports.  Another machine whose root fs is on
a SCSI drive booted without a problem.

I'll try to reproduce everything tomorrow, I have some wine and BSG 3x10 waiting for me :). Thanks for testing so far!
