Booting 6.0 RC1 with synced sources from today hangs

[Manfred Lotz]

Hi all,
I tried FreeBSD 6.0 RC1 whic hworked fine besides that when booting
after the message 
acd2: DVDR <NEC DVD RW ND-3540A/1.01> at ata3-master DUMA33

it took a minute or so to show the next message.


No I synced the sources and build a new kernel in order to e.g. try out
cdrecord which requires atapicam.

But now I can no longer boot:

acd2: DVDR <NEC DVD RW ND-3540A/1.01> at ata3-master DUMA33
Interrupt storm detected on "irq10:atapci0+"; throttling interrupt
source acd2: req=0x2593578 TEST_UNIT_READY semaphore timeout !! DANGER
Will Robinson! !
acd2: req=0x2593bb8 TEST_UNIT_READY semaphore timeout !! DANGER Will
Robinson! !
acd2: req=0x2593bb8 TEST_UNIT_READY semaphore timeout !! DANGER Will
Robinson! !
acd2: req=0x2593bb8 TEST_UNIT_READY semaphore timeout !! DANGER Will
Robinson! !
.... some more meesages regarding atapicam stuff ...
acd2: req=0x2593708 TEST_UNIT_READY semaphore timeout !! DANGER Will
Robinson! !


The the screen gets black and the first line shows garbled stuff...
and the system hangs
