Various issues with 2.5.2-dj6

Just got 2.5.2-dj6 building today and have the following to report:

system stability is very nice. Rock solid and responsive despite it
being experimental.

I have the kernel patched in the following order:
2.5.2
2.5.2-dj6
preempt-kernel
acpi (against 2.4.17 - all mispatches fixed except for some trivia in
Configure.help)
acpi-pci-irq-routing (obtained from LKML)

The following options are passed to the kernel:
pci=acpiirq root=/dev/hda7 ro

I can send my config to anybody who needs it.

Issue 1: kernel does not compile without SMP support (missing references
to global_irq_holder in sched.c)
Issue 2: Two IEEE1934 modules needed to have "#include
<linux/interrupt.h>" added (host.c and another one I forget)
Issue 3: Turning off hotplug (/etc/init.d/hotplug stop on a Debian
unstable box - updated today) gives the following oopses (captured by
"klogd -x") - see below.
Issue 4: Unmounting the drives read-only with Alt-SysRQ-U gives the
following oops and locks the box except for further Alt-SysRQ-* (mount
-o ro,remout /mount/point works fine) - see below.
Issue 5: Mouse (via /dev/input/mice) seems slugish this time (after a
fresh cold boot). Seemed fine first few times on 2.5.2-dj6 and fine
under 2.4.18-pre7 /dev/psaux.

Hope this helps the 2.5 effort and isn't just something stupid (or a
whole lot of stupid somethings) on my part.
