Well, no problem. I think the mouse is OK. However, you compared apples
with oranges by doing the tests on two different platforms (i.e. different
motherboards from different manufacturers) and the tests were not
exhaustive (incl. swapping hardware between computers to rule out card
problems). But see below...
(Anyway, I think we should take this off-list...)

Duh, pretty obvious, so why don't you pass on the output to me??? :-)
Well, don't need it anymore, I think.

That's because you probably need a separate mixer device or maybe the OSS
compatibility devices, don't know; ask the sound experts...
NOTE ADDED : read SoundPro in kernel-doc-<version>/sound; it talks about
mixer control problems for certain Windows Sound System cards (like your
cs4232 card) and advises to try out the ad1848-like mixer chip driver (as
included in the last modules.conf you included in this message).
This reminds me to next time also provide the output of lsmod...

Could be useful to enforce ordering maybe in the IRQ assignment by the
kernel...

Because according to your previous post you assigned IRQ 11 in the BIOS to
the SuperVGA card in slot 3. However, this type of video card doesn't need
an IRQ since it is a completely memory-mapped device. So, turn of the BIOS
IRQ assignment to VGA and additionally switch off the IRQ 11 allocation to
slot 3 (i.e. by putting it back to Auto; in fact, you should do that for
all the slots!!!). See below...

Mmm, I more and more start to believe the aliases for the other devices in
modules.conf does influence the device driver probing or(/and) (so) the
IRQ assignment order.

Ok, and how does the IRQ assignment look now in the BIOS. Please, give me

Well, OS/2 ignores the BIOS IRQ assignments and reprograms the IRQ
router in case the MP3's happen to be on a SCSI device. If not, it still
is an IRQ problem, not DMA one, I think(!).
Summary : SCSI card doesn't get the IRQ it wants. Sound seems to work,
regardless of isapnp configuration mode (i.e. manual or auto-detect).
Mouse seems to work fine too (there is no device file when there is no
mouse detected, i.e. in those case there is no PS/2 entry on IRQ 12 in
/proc.interrupts). Only consistent pattern is lock-up when trying to play
MP3's. Only reoccuring error message in /var/log/dmesg is IRQ assignment
to SCSI controller card. (Various BIOS setup-related quirks...)
TO DO : do the testing on the problem machine. If you get it to work but
are experiencing random lockup (but long enough after boot), try replacing
hardware ONE by ONE from the other (AOpen) machine.
Try the following setup strategy :
* Disable ALL interrupt assignments in the BIOS, except for USB (see
below). This includes putting ALL Slot<->IRQ associations back to Auto!!!
Only add them back ONE by ONE when some devices don't get detected during
boot (i.e. compare what you expect with what you find in dmesg and
/proc/interrupts), starting with the slot corresponding to the device
that is not found.
* Set IRQ 3 or 5 to Legacy ISA and see how the sound card and the NIC
interact (i.e. in /proc/interrupts). Put it to 5 if the sound card is
only really happy with IRQ 5.
* Disconnect any USB devices if they don't include your keyboard and
mouse, switch off temporarily IRQ assignm. to USB to prevent loading the
USB controller driver...(and resolve that remount error in /var/log/dmesg
when re-enabling USB)
* Change modules.conf to include all the top-level aliases you find in
RH7.3 (such as eth0, scsi_hostadapter, add usb-controller later when
re-enabling USB, ...)
( * Use the last settings for sound you sent me; this will give you a
working mixer and a synthesizer (it eats an IRQ# though...).)
* After boot, check for problems in /var/log/dmesg (such as the SCSI IRQ
problem :-P :-) and check /proc/isapnp for the sound card,
/proc/interrupts to see if all devices are active (you won't find VGA or
any switch off devices such as USB when it is disabled, ...) and
maybe lspci -v when you are playing with the Slot<->IRQ associations in
the BIOS.
When it works or doesn't work after many tries, please send me
/var/log/dmesg, /proc/interrupts, /proc/isapnp (or /proc/sys/pnp),
/etc/modules.conf, BIOS info (setting+boot), lsmod and lspci -v .
I hope this helps,
Good luck!
