How extraordinarly cute! This solves it! I'm currently listening to
Me, Mom and Morgentaler and burning a 4x CD without any slowdown, this
is great.
So I guess a "workaround" is to toggle DMA for my ATAPI bus. Indeed,
the burner is IDE and should be working on DMA mode to get optimal
performance.
The thing is that atapicam hides the DMA/PIO magic from the usual boot
messagesand there's therefore no way to see wether the device is in
DMA mode unless you compile in both cd0 and acd0 which I heard isn't
recommended...
A.
PS: what's the proper way to enable ATAPI DMA in the loader.conf file?
I don't see any flag WRT that there.. I'm tempted to add:
set hw.ata.atapi_cam=1
anywhere there...
