| Ooo, this is a fun one. CVS from about 22hrs ago.
| ata0-master: WARNING - SETFEATURES SET TRANSFER MODE interrupt seen but 
| task queue stalled
| acd0: WARNING - MODE_SENSE_BIG interrupt seen but task queue stalled
| Machine nonresponsive even prior to warning, takes >60s for warning to 
| display.
| 
| Machine is an IBM Netfinity 4500R, ServerWorks ROSB4 (pardon if I 
| misspelled.) Normally forces mode to BIOSPIO4. Any ideas? No changes to the 
| machine, prior kernel works.

I get this when I have a Pioneer DVD connected. I had to disable it in
the BIOS to get the machine to boot.

acd1: DVDROM <Pioneer DVD-ROM ATAPIModel DVD-120> at ata0-slave PIO4

Sometimes booting with media in the drive helps.
