Hi,
enclosed you'll find a bug report. I would be very interested
whether someone is able to reproduce the crash.
Regards,
Steffen
[1.] One line summary of the problem:
Complete freeze of system after trying to read:
"/proc/ide/ide1/hdd/identify"
if "ide-cd" ("/dev/hdd" is my IDE CD-ROM) is not loaded.
[2.] Full description of the problem/report:
Yesterday I had a complete lockup of my workstation machine after
doing a:
"cat /proc/ide/ide1/hdd/identify"
accidentally. "/dev/hdd" is my IDE CD-ROM drive. The problem only
occurs when kernel module "ide-cd" is _not_inserted_.
I can reprduce the crash very easily and regularly by trying to read
from "/proc/ide/ide1/hdd/identify" whenever the "ide-cd"-module is not
loaded.
I don't get any kernel OOPS or PANIC message neither on the console
screen nor within my log files... The system just stops totally,
CAPS lock and SCROLL lock start blinking. SYSRQ-magic-keys don't
function either...
Some information about my machine:

I tried to reproduce the crash on another machine running the same
kernel ("linux-2.4.19-ac4"). This machine has got also a VIA chip-
set and shows exactly the same symptom (= crash):

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt):
I'm sorry, I don't get any oops message. :-(
[6.] A small shell script or example program which triggers the
problem (if possible):
Just do a "rmmod ide-cd" (if it's inserted) and try to read from
"/proc/ide/ide1/hdd" (or whatever the file for your IDE CD-ROM drive
is).

Alan might be able to say better (e.g. this is a known problem) but I
would suggest trying to reproduce this on the latest 2.4-ac, which at
the moment is 2.4.20-pre2-ac3... much IDE work is ongoing.

Hi Robert,
thank you very much for your fast reply!

I've just tested "linux-2.4.20-pre2-ac3" on one of the two machines
("gateway") - I've had the same results.

Hi,
I was able to reproduce the problem described by Steffen Moser with
2.4.20-pre2-ac3+rmap14.
