Description Ed Bailey 2001-08-21 13:10:27 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.3) Gecko/20010802

Description of problem:
A system containing the CS5530 chipset experiences IDE-related problems
(anaconda unable to start from CD, DMA timeouts on heavy HD activity) when
DMA is enabled.  With DMA disabled (with either "ide=nodma" or via hdparm
-d 0), the problems disappear.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Attempt to boot from the 7.1 CD


Actual Results:  Anaconda under X would never start.  Complained about
corrupt shared libraries.


Expected Results:  Anaconda should have started under X.  Booting with
ide=nodma allows this to happen.


Additional info:

This was with the updated 7.1 kernel (2.4.3-12)  I'll attach a file
containing dmesg output and select entries from /proc/ide...
