It is the "magicdev" program causing the problem. I un-install it on my
systems since it isn't a requirement for the system to function. The
only thing is that you will have to mount the CD manually instead of it
being mounted when you put one in the drive.

Subject: Multiple devices on IDE cable
Date: 9 Mar 2001 19:21:55 +0100
We have a system with two IDE busses, using UDMA66. We initially tried to
put two hard drives on the primary, and a hard drive and a CD-ROM drive on
the secondary.
IDE connector 1:
master hard drive hda
slave hard drive hdb
IDE connector 2:
master CD-ROM drive hdc
slave hard drive hdd
In that configuration, the machine would freeze up intermittently. The
hard drive light would be stuck on, and it was dead to the outside world.
We're not 100% sure what caused it, but it seemed to occur more frequently when
we were actively using the b & d drives. We're now running an application
that's really using b & d, and also doing a large tar from b (to another
machine over the network). The result is that the machine crashes in a
number of hours.
We've tried disconnecting various combinations of things. Conclusions so far:
* without CD-ROM (but with all 3 drives), same problem.
* with CD-ROM and 2 drives, same problem (not sure we've tested all
possible permutations, but each test essentially takes 1/2 a day).
* with CD-ROM and 1 drive (hda), the problem seems to go away.
We've tried 2.4 kernel and 2.4.2. (For our application, it's critical that
we use 2.4 or higher.)
Does anyone know about this? Are we doing something wrong? Is there some
sort of race condition in some IDE driver somewhere? Is there a fix available?

Subject: USB mouse and screen blanking on IBM TP21...
Date: Fri, 09 Mar 2001 19:40:57 +0100
Hi all,
When on battery power my TP21 will blank the screen after several
minutes of inactivity. This is a good thing, as it conserves power.
The problem is that I use a USB mouse, and for some reason USB mouse
activity is not detected by the APM BIOS as activity. So browsing on
battery power results in periodial screen blanks which get me to dive
for the spacebar again.
This behaviour is not shown under a particular OS from Redmaond that I'd
rather wish I didn't have to inflict on my Laptop anymore. (But I like
to watch DVD's in that train sometimes so Windows sadly has to remain on
the HD for the moment.)
Does anybody have an idea on how to solve this? Other then just turning
of screen blanking in the bios.
TIA
Krist

A system call would be fine for that.

Subject: SonyVAIO PCG-Z600NE PCI (NOT USB) MemoryStick Recognition
Date: Fri, 9 Mar 2001 18:37:07 -0000
Hi folks,
I'm trying to use MemoryStick slot on SonyVAIO PCG-Z600NE,
and currently no luck.
Product Name "Z600NE" is a bit funny,
probably this is used for Europe domain.
I believe some "505" series should have same spedification.
Linux/OS does not recognize MemoryStick as HD at all.
What I can see is:
* This machine's Memorystick seems to be
connected to PCI not USB. <-- important!
So USB-MASS-STRAGE is no help.
Anyway, those below config=y but still no luck.
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_USB_STORAGE=y
* As above, SCSI config are included in kernel, but no help.
* "MemoryStick Controller" appears on /proc/pci
so device itself is existing anyway.
And it will act as ATA-Drive/Scsi(?) HardDrive
but Linux cannot recognized it as HD.
* Kernel parameter "hdc=autotune" is no help.
"hdc=247/2/16" (for example!) leads kernel panic,
no wander.
Kernel says, it's "non-ATA Drive".
Here is specs/logs which could help to tell the situation.
* Debian: woody(testing).
* Linux Kernel Version: 2.4.2 with devfs
* Eithernet/Audio devices are working fine.
* USB-Floppy is working on the same environment,
which is recognized as SCSI device and appers under
/dev/scsi/host0(snip)
* BIOS setup.
Menu [Advanced]
> Primary IDE Adapter [12073MB]
> Secondary IDE Adapter [None]
--> Submenu
Type [Auto]
This "Type" option has "ATAPI Removable"
and "CD-ROM" etc.
Any change for "Secondary IDE Adapter [None]" canNOT be made.
for example, change it to "ATAPI Removbale" from "None"
and Save(F10) and quit restart.
Then the menu "Secondary IDE Adapter" has been back to [None].
No way to change it, as far as I have tested.
Anyway, on the same BIOS configration, Win2K can recognize
memorystick properly.

I'd complain to whoever gave you the cable-modem. There's no
excuse for handing out something that doesn't doesn't act as a

The cpuid returns more than serial number. It appears that disabling
cpuid does not disable that instruction; instead it disables a subset,
the cpu serial number. Other abilities seem to remain intact. If you
have nasm, try this on a machine with cpuid disabled, and you'll still
get MMX detection to work. Two files are shown, mmx.cxx (C++), and
mmx_detect.asm (nasm/Intel format):
nasm -f elf mmx_detect.asm -o mmx_detect.o

I have an Aureal Vortex2 as well as the three Hi-Val PCI-338 (Free after
rebates) sound cards and decided not to use them mainly because there is no
source code for the driver for any aureal chipset. From now on, I will
stay away from any Aureal sound card unless someone has come out with the
source code for the driver (not the binary object files). I believe
someone has the source code for the Aureal drivers but s/he can't not
release it to the public main because it is copyrighted to Aureal Inc.
which already gone out of business.

My only suggestion would be to reverse the devices on the second ide
chain--make the hard disk master and the CD-ROM slave; it is possible
that the CD-ROM, being so much slower, is causing the problem.
Good Luck!
