	Thanks a lot! Could you please MFC these fixes to 8/9/9.1 as
	apparently r238666 affects all and r238673 at least all !x86
	architectures and not just sparc64?

	Also, could you please look into why ATA_CAM breaks ATAPI CAM/
	causes data corruption for/with certain controllers driven by
	ata(4)? At least the the ALi ATA controller in Blade 100, which
	AFAIK you own one of, is affected, but again, this problem is
	also seen with ITE ones on x86.

I updated to r239940, and now the cdrom seems to work ok.
I can mount cds and burn with cdrtools-devel-3.01a08,1.
This is on
cpu0: Sun Microsystems UltraSparc-IIIi Processor (1503.00 MHz CPU)

Many thanks
