Bug 8251 – livecd and DMA problems

• Status: RESOLVED FIXED
• Product: Gentoo Release Media

[Description Yavor Goulishev 2002-09-23 02:22:03 UTC]

I have Gentoo 1.2 installed, but I used hdparm -d 0 to
disable the DMA for my ACER 32 X CD before unzipping
stage files. I get errors if the DMA is enabled :-((

Now when Gentoo 1.4 rc1 is ready I'm stuck with kernel
panic at the boot - when tyring to populate the links.
The livecd doesn't take any kernel params

The livecd doesn't take any kernel params  it
automatically boots, though I'm not sure there is
param for stopping DMA. Anyway it would be helpful in
some situations to be able to pass params.

Also are you going to support normal install CD (not
live CD with installed Gentoo) like in 1.2 ? Or can
you make it optional? This part with the mouting and
extracting really fails on old cdroms.

I'll try to add the ability to disable DMA to the livecd for 1.4 final.

[Comment 3 Daniel Robbins (RETIRED) 2003-01-10 02:04:39 UTC]

OK, you now have the ability to specify boot options like ide=nodma which will
turn off DMA.

Moving these so we can remove the "Install CD" component from "Gentoo Linux".

I apologize to everyone for this spam, but according to the bugzilla developers,
this is the only reasonable way to do this.
