Subject: PROBLEM: CR-RW works on Win98se but not Linux 2.4.18
Date: Sun, 12 May 2002 11:17:37 -0500 [thread overview]
Message-ID: <3CDE95A1.7F3D005@lightfirst.com> (raw)
PROBLEM: CR-RW works on Win98se but not Linux 2.4.18
NOTE: This is probably the Via chipset data corruption bug
I have installed a Philips PCRW2412 CD writer (24x12x40x). It works
fine when I boot into Windows 98se, but does not work when I boot into
Linux 2.4.18. Gtoaster and cdrecord give no errors, but when I compare
to the original a few files have permanent compare errors (different
files for different CDRs); writing while booted in Win98se gets no
compare errors (comparing while booted in Linux 2.4.18). I have tried
3 other CD writers with similar results, except that an old HP 4x2x10x
writer worked mostly (compare errors about 1 out of 10 CDRs). The
system is as idle as I can make it, but CPU activity does not seem
to affect this.
I have upgraded everything I know how to:
RedHat 7.2 (includes cdrecord 1.10)
BIOS 1008a (latest from the manufacturer, Asus A7V133)
Kernel 2.4.18 (configured and built it myself (:-)) -- system
boots just fine using this or the RH 7.2 kernel (2.4.7-10).
CD-R problems are the same for both kernels. I had to
config it for PentiumIII, because the Athlon config has
unsatisfied external _mmx_memcopy() in some modules. I
used PCI access = BIOS (see below).
>From the success in Windows without the updated "4-in-1" driver, I
believe that the BIOS is configuring the PCI and IDE systems correctly
(that is Via's way to fix the bug). This implies that Linux is re-
configuring them incorrectly. I did configure the Kernel to use "BIOS"
access mode for PCI, hoping that would preserve the BIOS settings which
work in Windows, but I still get errors.
Here I describe things with a single harddisk (master) and the CD-RW
(slave) on the first IDE cable. I have a second harddisk (master) on
the second IDE cable; I can copy ~700 MB ISO images between drives
(hda and hdc) without errors, so the most common manifestation of the
"Via chipset data corruption bug" does not affect me (I unmounted
/dev/hdc while burning, to make sure cable-to-cable was not the
problem). I also had these errors in an older configuration with both
harddisks on the first IDE cable and the CD-RW on the second. Both
cables are 80-wire; trying the CD-RW on a 40-wire second cable still
had errors (did not try that in Win98se). I am of course using
ide-scsi for the CD-RW drive.
[I seem to recall comments in via82cxxx.c which said there
is a bug in the 40-wire detection; this may have compromized
my test with the 40-wire cable.]
So I think I have eliminated hardware problems as the source of these
errors. Does anyone have a clue? Is there some special kernel CONFIG
I need to select? Do I need to discard this motherboard and start over?
I recall seeing a Windows program which dumps some PCI config registers,
and the article discussed how to change them to fix this problem -- is
there such a program for Linux?
A Google search on "via data corruption bug" returns volumes of
information, but I cannot separate the wheat from the chaff....
I have asked this on several Linux newsgroups, but got no answer.
Thanks for any insight or assistance....
