[olug] RE: HDC: Lost Interrupt Error

[CM Miller]

I generally don't give up so easily, so after not
getting an my problem answer here I posted to 


http://www.linuxjunior.org


Someone advised that I modify /etc/sysconfig/harddisk
and uncomment the following: 

USE_DMA = 1 

It works, but now I want to know, why?  

DMA, I suspect is Direct Memory Access and here are
some of the comments above this line 


# These options are used to tune the hard drives -
# read the hdparm man page for more information

# Set this to 1 to enable DMA. This might cause some
# data corruption on certain chipset / hard drive
# combinations. This is used with the "-d" option


thanks

It varies, sometimes right away, sometimes 5 or 10
minutes later.

Nah, I don't think it is an error with XMMS, my
research on this points to two things:  Either
conflict with ides or enable multi-mode for my kernel,
which I have never heard of before.

Then I am stumped if you and I have the same output
under /proc/interrupts and /proc/ioports

This is something that I can 'workaround', but I 
know there is a solution out there.
