growisofs && non aligned DMA transfer (7.0R)

[Matthias Apitz]

Hello,

I wanted to add a file to an already written DVD+RW (written a day
before on the same system) with

# growisofs  -M /dev/cd0 -r -T -J -joliet-long -v directory

This produced tons of error messages via syslog as

Jul 11 13:45:30 rebelion kernel: ata0: FAILURE - non aligned DMA transfer attempted
Jul 11 13:45:30 rebelion kernel: acd0: setting up DMA failed

and the only way to get the system back to a usable state was rebooting
it;

this is with FreeBSD-7.0R; what I have done wrong?

thx

	matthias
