by I have a DOS partition on /dev/hda1 and a LINUX partition on
/dev/hda2. There is also /dev/hdb with a Windows NT partition.
After booting, the first time I give the 'ls -l' command to the DOS
partition, /dev/hda1, the following message appears on the screen
after a 15 second stall:
hda: irq timeout: status=0xd0 { Busy }
hda: disabled DMA
hdb: disabled DMA
ide0: reset: success,
then the output to the 'ls -l' command finally appears.
Subsequent 'ls -l' commands to /dev/hda1 do not yield the message
during the same LINUX session, nor do I receive the message if I give
the 'ls -l' command to any other partition; i.e., /dev/hda2 (the LINUX
partition itself) or /dev/hdb1. Sometimes, but rarely, the message
appears at boot time, just after the partition check, or immediately
prior to the appearance of the login prompt.
So far I have not noticed any other problems which are unambiguously
related to the phenomenon.
The problem started after I had to change from a Microsoft busmouse
(IRQ was 5) to a PS/2 mouse (IRQ is 12) because Windows NT would not
work with the former. The new PS/2 protocol works with X-Windows.
Due to the timing, it looked like a hardware problem to me, but my
dealer says that everything is set up properly.
I have installed an new kernel (2.0.30) and have reinstalled some
library files from setup, but the problem still occurs. It also
occurs with two other Linux systems I have installed on a zip drive
and on /dev/hdc.
I am wondering if it is some type of memory conflict.
I would appreciate any advice someone can give on the matter. Should it
help, I am including the current boot-time output from 'dmesg.'
