Package: debian-installer
Version: Sarge RC1 (ISO-Image 1 of 13)

I'm testing Debian CD Sarge i386 RC1, ISO 1 of 13.

Problem: During the installation of the packages (from IDE DVD-ROM) I 
get a "hdb: DSC Timeout" (almost) every time. AFAIK a DSC timeout is a 
non-fatal condition. But after it my system gets stuck in a  "cdrom 
access - DMA timeout - ATAPI reset" loop and nothing responds anymore.  

It's strange that the problem only occurs during the package 
installation phase. The base install works everytime (I tried 
approximately 6 installations) and I can even mount the whole CD 
manually and copy the content into a directoy on the harddisk 
(BTW: that's why I'm sure that the CD has no errors). I think a specific 
access pattern during package install triggers the failure.

Workaround: before the installation of the packages invoke a shell and 
disable the dsc_overlap feature:
echo "dsc_overlap:0">/proc/ide/ide0/hdb/settings 

Proposed solution: AFAIK dsc_overlap is an advanced feature that was 
used before only with SCSI devices (disconnection). Obviously my 5 
years old hardware has troubles with it. My suggestion is to disable 
dsc_overlap for old hardware or even for all hardware - at least during 
installation. 

Hardware:

Mainboard: Tyan S1590S Trinity 100AT /* nice upgrade board */
Chipset: VIA MVP3 (82C5xx)   /* *cough* CRAP! *cough* */
CPU: AMD K6-II / 500 MHz
IDE HD (WDC WD450AA-00BAA0) on hda (installation target)
IDE DVD-ROM (Asus E616) on hdb (installtion source)
IDE HD (Maxtor 34098H4) on hdc (unused)

Closing, this sounds like it was a hardware bug.
