SubjectComplete system freeze with "linux-2.4.19-ac4"
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):

[3.] Keywords (i.e., modules, networking, kernel):

IDE subsystem, VIA chipset, modules (ide-cd.o)


[4.] Kernel version (from /proc/version):

Machine 1 ("pc01"):

Linux version 2.4.19-ac4 (root@pc01) (gcc version 2.95.3 20010315 (SuSE)) #52 Fri Aug 9 18:40:47 CEST 2002

Machine 2 ("gateway"):

Linux version 2.4.19-ac4 (root@gateway) (gcc version 2.95.3 20010315 (SuSE)) #10 Sun Aug 18 15:14:15 CEST 2002


[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).

[7.6.] SCSI information (from /proc/scsi/scsi)

SCSI subsystem was not active (on "pc01").

If I load the modules, I get:

| pc01:~ # cat /proc/scsi/scsi
| Attached devices:
| Host: scsi0 Channel: 00 Id: 03 Lun: 00
| Vendor: YAMAHA Model: CRW8424S Rev: 1.0j
| Type: CD-ROM ANSI SCSI revision: 02
| Host: scsi0 Channel: 00 Id: 06 Lun: 00
| Vendor: HP Model: HP35470A Rev: T603
| Type: Sequential-Access ANSI SCSI revision: 02

On "gateway" there is no SCSI hardware present.
