Hi,
I still have problems with the VIA Apollo southbridge (Kernel 2.4.2 (Redhat 7.1) and
Kernel 2.4.4).
In rare circumstances,
there ist still file-corruption. I use an ASUS A7V133 (Revision 1.05,
including Sound + Raid). My tests:
- copying 4 GB of CD-ISO-Files from Promise Secondary Master to Promise
Secondary Slave. After that "diff -r srcdir destdir". Test was
succesfull, no differs, even after 15 executions
- (same test with small files)
copying 4GB of small files (50 to 500 KB) from Promise Secondary Master
to Promise Secondary Slave.
1st run of "diff -r srcdir destdir" -> no differs
2nd run of "diff -r srcdir destdir" -> 2 files differ
3rd run of "diff -r srcdir destdir" -> 1 file differs
4th run of "diff -r srcdir destdir" -> 1 file differs
5th run of "diff -r srcdir destdir" -> no differs
- I d did the same tests on the Promise Primary, same results. Also on
the the VIA Secondary but my feeling is that there are even more
corruptions.
I stripped the machine to the bone, PCI-VGA only, same results.
I cannot say for sure, but before I stripped my adaptec SCSI-Card, there
may even been "differs" after copying from SCSI-Disk to SCSI-Disk. Off
course I thought other parts of my Hardware was flacky (e.g. RAM...),
but I swapped everything: RAM from different manufacturers, IDE-Cables,
CPU (Duron 900 -> Duron 850), VGA-Card, I tried the most conservative
Setting in the A7V-Bios, Bios-Update 1003 -> 1004 -> 1004 beta3, UDMA6->UDMA2 all to
no avail.
Any hints?
