I attempted to boot linux-image-2.6.17-2-686-bigmem and also had this
failure. This kernel was from backports.org, _but_ only these changes had
been made:
linux-2.6 (2.6.17-8~bpo.1) sarge-backports; urgency=low
* Rebuilt for sarge.
* Built using gcc-3.3 and python2.4.
* Disabled ABI check.

so I think it is worth following up to this bug.
I will of course send this report to the backports people too.
Note that linux-image-2.6.16-2-686-smp from the same source worked
(same level of changes, just a recompile basically).
The console message right before the hang was
ts: Compaq touchscreen protocol output
The first few lines after that are
BUG: unable to handle kernel NULL pointer dereference at virtual address 0000000c
printing eip:
c020ab74
*pde = 039a5001
*pre = 00000000

I am not using the bpo libc6-i686 package.

This is a SMP-aware kernel,
% grep SMP /boot/config-2.6.17-2-686-bigmem
CONFIG_SMP=y
# CONFIG_X86_BIGSMP is not set
CONFIG_SUSPEND_SMP=y
CONFIG_X86_FIND_SMP_CONFIG=y
CONFIG_X86_SMP=y
I have the hardware attached to a KVM and the serial port connected to a
serial concentrator.
The relevant bits of /boot/grub/menu.lst are
serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1
terminal --timeout=5 console serial
kernel /boot/vmlinuz-2.6.17-2-686-bigmem root=/dev/sda2 ro console=tty0 console=ttyS0,9600
I saw the comment about blacklisting 8250_pnp but did not try this.
I have hotplug-utils and udev installed, I don't understand why
/etc/hotplug should have anything to do with this problem but perhaps it
does. FWIW,
% ls /etc/hotplug/blacklist.d
libsane
This file belongs to the (sarge) libsane package and should have no
relevance to this discussion.
% dpkg -l udev
