I wonder if you can mount a CD with a GENERIC kernel?
I also wonder if you can avoid the "interrupt storm" with your custom kernel
but by disabling atapi dma? (hw.ata.atapi_dma="0" in /boot/loader.conf)
If this kernel boots, can you mount a CD?
If you get some free time and feel like messing around with it, I'd be curious
what you find.
Regards
