Good day.
Under any of test7-smp and test7-up and test8-pre1-smp, attempting to
"modprobe sound" causes an OOPs; and on test8-pre1, it further locks the
box up rather rudely.
test6 works fine with no complaints, and logs the following:

test7-smp logs the following:

This oops did not appear to log in /var/log/messages.
After this oops, attempting to cat either /proc/ioports or
/proc/interrupts also causes an oops
One oops was decoded as attached, decoded_oops_cat.txt
the module "soundcore" is left loaded, with a non-zero refcount
(unsurprising, since a module that required it, namely sound, crashed
during initialization), and the system oops's again on shutdown - again
this did not log.
I noted an earlier post on the list with someone having trouble with esd
oops'ing, it would seem these two are related; another oops attached
shows a prior attempt - note though that the modules / ksyms used are
from a different boot, but should still be valid.
What have I concluded from this:
* sometime between test6 and test7, soundblaster support was broken bad;
and isn't fixed in test8-pre1
* the problem is very reproducible, and not smp-specific
Oh, yes. hardware details:
Genuine Creative Labs SoundBlaster AWE32 at IO 0x220, IRQ 5, DMA 1,5
Abit BP6 with dual Celeron processors
realtek 8139 nic
matrox mystique with 2 Mb vram
seagate ata66 hdd off the onboard HPT366 controller
More details / tests available upon request. if I get time I'll have a
look at the patches and try and determine exactly what broke and where;
but I don't know if I'll find time, alas.
