Put me in the "it works for me" camp also.  Do we have the definitive answer

Definitely *not* "APIC support on uniprocessor" related.  At least one

panic problem, I've got a Cyrix.  Mine's a MII 300 (233 MHz).  Works fine
with 2.4.5 and prior kernels.  Didn't try any of the pre-2.4.6 or -ac

Several years ago I ran into a problem with similar symptoms on an old

That fixed the "wrong size" problem nicely.  Thanks!

AGP support on this beast (Tyan S1590S / Apollo MVP3) is still broken,
however.  I'll try the new NVIDIA driver (as someone suggested -- thanks
for the steer!) and see if that helps.  If there's an NVIDIA person

yes, BUT...

The "Documentation/mtrr.txt" file says "... 4 megabytes, which is
0x40 bytes (in hexadecimal)."  The math is correct: 1MB == 2**20
== 0x10 the last time I checked.  Unfortunately, when I execute

echo "base=0xd800 size=0x10 type=write-combining" >| /proc/mtrr

I get a 2MB region instead of the 1MB region I expected...

reg00: base=0xd800 (3456MB), size=   2MB: write-combining, count=1
reg01: base=0x000c (   0MB), size= 512KB: uncachable, count=1
reg07: base=0x (   0MB), size= 256MB: write-through, count=1

Similarly, the NVIDIA driver attempts to create a 32MB write-combining
region by passing a size argument of 0x200, and fails because the
underlying mtrr code tries to carve out a 64MB region whereas my video
card has only 32MB of RAM.

Looks like an off-by-one (bit) error to me.  So...  Is this a legitimate
bug sighting, or is my analysis faulty?

another Cyrix/mtrr problem?

2001-03-13 Thread Bob_Tracy

Since I've seen a few other posts on the subject, I might as well
poke my head out of the foxhole long enough to get shot at :-).

System is a Tyan S1590S motherboard (Apollo MVP3 chipset) with
Cyrix MII 300 processor, NVIDIA GeForce2 MX AGP video card, 2.4.2
kernel, XFree86-4.0.2, and the NVIDIA 0.9-6 driver.  Everything worked
great with the 2.4.1 kernel, XFree86-4.0.1, and the NVIDIA 0.9-5 driver
(patched to compile with 2.4.X kernels).  With the current setup, the
NVIDIA driver fails to set up a desired write-combining memory range and
disables AGP support.  If I try to force the issue by configuring
the NVIDIA driver to use the kernel's AGPGART support, the console
switches to graphics mode and then becomes completely unresponsive
to input other than tracking mouse cursor movement.  The only safe
way I've found to restore console functionality is to login remotely
and reboot the machine: killing the X server and associated apps won't
do the trick.

If anyone is interested in working this issue, I can/will forward a
copy of a representative /var/log/XFree86.0.log file showing what
happens for the case of using the NVIDIA driver's internal AGP support.
Within the log file are the following two lines that pretty much sum
it up:

(WW) NVIDIA(0): Failed to set up write-combining range (0xd800,0x200)
(II) NVIDIA(0): AGP is disabled

Jeff Hartmann (AGPGART support) thinks this is probably a MTRR issue.
I'm leaning that way, given a recent posting by someone else having
MTRR problems with his Cyrix 6x86.

Anyone that can help troubleshoot this and/or provide a fix would be
greatly appreciated.  Thanks in advance!

"our" code.

 Can you verify that..
 
  a. You have MTRR support compiled into the kernel.

yes

  b. You have a /proc/mtrr file

yes

  c. You can add/delete ranges using /proc/mtrr
 (See Documentation/mtrr.txt for info on how to do this)

yes, BUT...

The "Documentation/mtrr.txt" file says "... 4 megabytes, which is
0x40 bytes (in hexadecimal)."  The math is correct: 1MB == 2**20
== 0x10 the last time I checked.  Unfortunately, when I execute

echo "base=0xd800 size=0x10 type=write-combining" | /proc/mtrr

I get a 2MB region instead of the 1MB region I expected...

reg00: base=0xd800 (3456MB), size=   2MB: write-combining, count=1
reg01: base=0x000c (   0MB), size= 512KB: uncachable, count=1
reg07: base=0x (   0MB), size= 256MB: write-through, count=1

Similarly, the NVIDIA driver attempts to create a 32MB write-combining
region by passing a size argument of 0x200, and fails because the
underlying mtrr code tries to carve out a 64MB region whereas my video
card has only 32MB of RAM.

Looks like an off-by-one (bit) error to me.  So...  Is this a legitimate
bug sighting, or is my analysis faulty?

ATAPI CD burner with cdrecord > 1.6.1

Kernel version is 2.4.1.  For versions of cdrecord later than 1.6.1
(1.8.1 through the latest 1.10 alpha verified), attempting to burn a
CD results in a SCSI error of some kind.  Here's some representative
output from a "dummy" burn session with cdrecord-1.9:

depmod -a and 2.4.0

2001-01-11 Thread Bob_Tracy

Maybe I missed the discussion, but why might "depmod -a" result
in every module getting installed?  This didn't happen under any
of the 2.4.0-testX releases that I recall, and I ran every one of
those and the prerelease without this "trouble".  Gotta say, the
screen output from running "lsmod" with everything installed is
pretty darned impressive :-).  Another oddity that someone else
already reported: the ipv6 module shows a reference count of -1.

Yes, I'm running modutils-2.4.1, and I get the same results with
modutils-2.3.15.

I tried the submitted patch for ip_fragment.c, and there's still
no joy on that one unstable machine in my sample set.  At this
point, I should probably go back through all the pre-12 patches
and see if the problem scope can be narrowed a bit.

This is consistent with the lockup I reported several hours ago.
In the case of my "unstable" 2.4.0-test12 machine where "startx"
worked fine for "root" but not for a normal user, the "root"
account is local.  The normal user account home directories are

Good spot!  I've done a little mucking around with the networking
code, i.e., no promises, but maybe I can come up with a fix.

This one is going to be fun to track down.  So far, with a personal
sample size of three machines, 2.4.0-test12 is stable on two, locks
up in a predictable and repeatable manner on one.  First, the stable
machines:

(1) P150 MMX Toshiba Tecra 730XCDT notebook, egcs-2.91.66, openwin
with XFree86 3.3.6.

(2) Cyrix 6x86 MII 233, egcs-2.91.66, AfterStep with XFree86 4.0.1,
NVIDIA-0.9-5 video driver.

The unstable machine:

Gateway PII 333, egcs-2.91.66, AfterStep with XFree86 3.3.6.
Running "startx" as "root" --> ok: no problem.
Running "startx" as normal user --> I get as far as the grey moire
pattern with the black "X" cursor in the center of the screen, and
the machine locks up solid.  Cannot switch consoles, machine doesn't
respond to pings (much less remote access attempts), no disk activity,
no "oops" messages in any of the logfiles.  Absolutely repeatable.
Machine works fine with earlier kernels.

Does anyone have a feeling one way or the other as far as this being
related to the CPU type?  I can try building a pre-PII CPU kernel on
the unstable machine and see if that makes any difference.

Executive summary: a free driver is in its infancy, and you're
more than welcome to join the debugging effort.  If you *must*
have sound capability, go to http://www.opensound.com and get the
OSS driver: that will run you $15 for the base driver, and
another $15 for the ESS Maestro add-on.  It works well on my Dell
Latitude CPx.  You can try before you buy, and the 2.4.X kernel
support is pretty good: new driver versions lag the release of a
2.4.0-testX kernel by less than a week in most cases.

Good luck!

 Any hints/clues/etc welcome.

Welcome to the "wonderful" world of the Maestro 3i.  You'll find
the following URL to be of interest...

Adaptec 2930U2 followup

2000-09-02 Thread Bob_Tracy

Thought it might be worth a followup report in case anyone was
interested.  All the problems I was seeing with my 2930U2 went
bye-bye when I replaced my bottom-feeder M537 VXpro motherboard
with a Tyan S1590S.

Current setup is Linux 2.4.0-test7 with the aic7xxx driver
compiled in.

www.crucial.com won't talk to 2.4.0-test7 system

2000-08-29 Thread Bob_Tracy

I *thought* I wanted to buy some memory from Crucial :-).  Can't
get there from here with my 2.4.0-test7 machine, but Win95 seems
to be ok, and 2.4.0-test5 worked ok from a different location
yesterday.  Has anyone else seen this kind of thing that might shed
some light on the matter?  Here's what tcpdump saw:
