5.3 interrupt storm (atapicam) and I/O error

[ad5gb]

Daniel

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
