This is definitely the wrong list to ask this question - and therefore,
I'm only phishing for pointers.
Three months ago I bought a machine (from a vendor I won't name, because
it was HP), that featured a 320 Gbyte IDE drive and a (removable, but
kept installed in my case) 320 Gbyte SCSI device).
The Stable install went fine - IDE drive got /dev/hda1 (swap) and
/dev/hda2 (/ - the rest of the device). SCSI drive got /dev/sda1
(/scratch - I need lots of it).
So far, so good. I downloaded the e1000 ethernet driver, because it
wasn't included in stable's 2.6.18-5 kernel. Compiled, modprobed,
dhclient'ed to my ISP's modem, all OK.
Changed /etc/apt/sources.list to exclude the DVD and include
deb http://ftp.nl.debian.org/debian testing main contrib
and apt-get update && apt-get dist-upgrade'd away.
Unfortunately, the resulting system (unlike the original from the DVD)
won't boot - it can't find the boot device. It does (helpfully) display
the message that the root device might be renamed (/dev/sda2), but
booting with that root device doesn't bring up the system.
Something rather fundamental must have changed (probably in udev)
between "stable" and the recent "testing" system - but what ?
