I wanted to try sarge by swapping out my main hard drive and putting in
a spare 10GB drive just to see how it's like. Installation was easy
(despite my need for manually configure network settings) and base installation went fine, but...

Rebooting didn't finish. The kernel booted, but after a while I just got
my monitor shut off, and trying to switch between consoles didn't help.
ctrl-alt-del initiated reboot sequence so I didn't need to do a cold
boot, but that was it. The same results were had in the "recovery"-mode.
I guess the installation of other packages (besides the base system)
should have started (?), but I have no idea what happened after the
screen went blank.

I have a Radeon 9600XT graphics adapter, which might be the cause of incompabilities, ie. framebuffer driver crashing the display or
XFree86's radeon-driver doing the same. Though does Debian use fb and
does the XFree86 even start at that time (first boot after base install)?

The last messages I see when booting are:
1) various USB messages (over one full screen of them)
2) just before monitor shutting itself, something about
"xxxx
net
pci" or something like that... hotplug things? Those are shown only
for a fraction of a second, after the USB messages, before the monitor
goes off.

It seems that most of the failures people are getting installing rc1 are because hotplug loads unsafe kernel modules, including hardware
watchdogs, and frame buffer modules that don't work right. It doesn't
help that as you noticed hotplug brings in all these unnecessary modules
even in single user mode.

Your problem sounds like hotplug loading a bad frame buffer module. Try
booting in emergency mode ("linux emergency"), remount the root
filesystem read-write ("mount -o remount,rw /"), remove
/etc/rcS.d/S40hotplug, then you should be able to boot without this
problem. If you can send us your lspci and lspci -n output, we can
probably determine which module hotplug is loading to cause your
problem, and fix it.

Thanks, I'm writing this now on Debian. The removal of S40hotplug allowed
sarge to boot properly and finish installation. The lspci and lspci -n
outputs are similar to those I posted from SUSE just before your e-mail, so
you can check this bug's page for those. The only exception is that USB Controller lines were a bit more verbose in Debian with "VT82xxxxx UHCI USB
1.1 Controller" included.

As a side note, booting in emergency mode required not exactly that, it required adding 'emergency' to the grub's kernel line.

Additional note regarding installation: exim's configuration, which seemingly comes up also when you just select the desktop packages, is probably odd for many people. It didn't even state what exim is at first, and doesn't say something like "it's safe to select the default here if you don't know what's this all about".

Other than this, Debian installation went nicely. One rant is that KDE wasn't installed with the Finnish language even though I chose it as the
installation language, and what's worse Finnish keyboard map was not
configured in KDE. But this is probably not a place for this.

Maybe, but the default configuration will not load any module for the
display PCI class.

If you want to help finding which module breaks your system please
run *AS A USER* "/etc/hotplug/pci.rc start", it should display which
modules are going to be loaded (and fail loading them, because you are
not root). Then try to manually load each of them with modprobe and
report which one crashes your system.

I know that's not true, because hotplug on fresh d-i installs has taken
to loading the matroxfb module for my test laptop, which yields a very
nice highres console. And when I disable hotplug, it stops being loaded.
Maybe you have a bug?

Ah, so that's how to get the list.

I don't know... Fumitoshi UKAI worked on this. Please attach your /etc/default/hotplug file, it should contain IGNORE_PCI_CLASS_DISPLAY=true.

I don't know... Fumitoshi UKAI worked on this. Please attach your /etc/default/hotplug file, it should contain IGNORE_PCI_CLASS_DISPLAY=true.

Note that in hotplug 0.0.20040329-12 (which probably used in d-i rc1), IGNORE_PCI_CLASS_DISPLAY is effective on only 2.6 kernel, since it checks
sysfs pci device class and this is not used on 2.4 kernel.
In hotplug 0.0.20040329-14 (which in sid), IGNORE_PCI_CLASS_DISPLAY
should be effective on 2.4 kernel too, because it now see whether module driver's path is in drivers/video or not by IGNORE_PCI_CLASS_DISPLAY.

Also note that 0.0.20040329-12 has minor bug to check blacklist for some modules (such as i810_tco, confusion '-' and '_' in module name, both may be used), which also has been fixed in 0.0.20040329-14.

Fumitoshi UKAI

It gave the following ones: radeonfb, usb_uhci ("blacklisted"),
via-ircc, 3c59x (already loaded), ohci1394, emu10k1-gp, btaudio and bttv.

And yes, 'modprobe radeonfb' crashed the monitor.

/etc/default/hotplug:
# hotplug configuraton file

#

So, as Fumitoshi said, IGNORE_PCI_CLASS_DISPLAY doesn't seem to work.
Radeon 9500-9800 gfx cards are quite common, so this will hopefully get
fixed.

I encountered this bug as well. I did a 'dist-upgrade' from woody with
a 2.4 kernel, rebooted and got a garbled display.

Turned out to be that IGNORE_PCI_CLASS_DISPLAY doesn't work, and loading
rivafb was the problem. Installing 0.0.20040329-14 from unstable fixed
the problem.

IMO, this bug priority should be raised. I was lucky enough to have a
dual boot (sarge and woody) machine that I could use to diagnose the
problem-- but with the console being unusable even in single user mode,
many will just give up on sarge.

Note that on my system, it is 'rivafb'. The original poster had
problems with 'radeonfb'.

So the bug with $IGNORE_PCI_CLASS_DISPLAY and 2.4 kernels is fixed in
unstable.
I encourage the d-i people to reassign this bug to the appropriate
kernel package.
