I have a Dell Inspiron 6000d which has a SATA hard disk and PATA optical drive. The performance for the hard disk is good, but the optical drive's performance is very poor, I can't turn on DMA. I used a kernel patch that got both drives working well, but it caused my kernel to be unstable (random lock ups). Here is a discussion of the patch: http://www.math.ucla.edu/~jimc/insp6000/p-disc.html#cd I searched the web more and found a discussion on the kernel parameter atapi_enabled=1, but that didn't work for me either. http://comments.gmane.org/gmane.linux.kernel/351063 This is the kernel I'm using: kernel-2.6.12-1.1381_FC3 Any advice, tips or hints? Thank you.
