Problems with Yamaha opl3sa2 under 2.4.20 and ongoing PCMCIA & USB problems on 2.6.0-test2

Hi,
	I've recently set up Linux 2.6.0-test2 on my laptop (Toshiba Protege
7010CT) which is running Slackware 9.0.  I've also set up the default
Slackware kernel so that I can run both kernels concurrently.

	So far, I've had minor problems with 2.4.20, but some even worse
problems with 2.6.0-test2.

Under 2.4.20:
	Everything works flawlessly, except the sound card (Yamaha OPL3-SAx)
refuses to work, the opl3sa2 driver does not recognise the card.

Under 2.6.0-test2:
	- Most things work nicely, even runs faster.
	- MySQL refuses to start (already noted on this list)
	- PCMCIA locks hard when adding and removing PCMCIA cards, even if I
run 'cardctl eject' first.
	- My combo network card & modem "Xircom RealPort Ethernet 10/100+Modem
56" only partially works.  Network works if I load 8250_cs, but
otherwise, the pcmcia-cs utilities try loading serial_cs.
	- My USB 2.0 hard drive box (aka IDE-TO-USB) does not function.  It
detects it, and automatically loads usb_storage, but I get an error
message saying the device was not found.

At the moment, I'm willing to stick with Linux 2.4.x, eventually I'll
upgrade to 2.4.21 or 22, depending on which is out, if I can get the
soundcard to detect.  However, I think getting Linux 2.6 fixed would be
the better option.

Is there something I might have missed in the kernel setup, or the
configuration of pcmcia-cs that needs to be changed?

Is it possible to, say, backport the opl3sa2 driver to Linux 2.4.2x?

Thanks,

This may be due to the screwups in the TI cardbus bridge code.
2.6.0-test2-bk<whatever-last-night-was> should have these problems
solved.

It's not clear what's wrong here.  Add into /etc/modprobe.conf an
alias for serial_cs to 8250_cs and everything should work.

What are the exact kernel log messages you got?
What does /proc/bus/usb/devices show when the device is plugged in?
Do you have SCSI disk support built into your kernel or loaded as a
module?

thanks,

Hmm i wonder how that got broken..

I'll fix the 2.4 one instead, there are a number of differences in the PnP 
system in 2.5 and 2.4 which would make backporting more work (with more 
likelyhood of bugs being introduced).

Thanks,

Could you please send me /var/log/dmesg from 2.4 and 2.6
