2.5.7,8-pre2 and USB

[Rob Hall]

Hi all,
	I'm running a Tyan Tiger Dual Athlon motherboard(S2624). This board has an
OHCI USB host controller on-board... I recently compiled 2.5.7, only to find
that the machine halts as soon as the USB HC is detected. Same problem arose
with 2.5.8-pre2.. Has the location of the USB init been changed? If I
recompile the kernel with USB support as modules, and load the appropriate
modules via init script, it works perfectly. Just wondering if this has been
reported by anyone else, and if it is a known issue, what is the cause and
is there a patch yet?


Thanks

	My bad everyone, the model number on that motherboard is S2460. 

Thanks

Which previous kernel did compiling the usb-ohci driver into the kernel successfully
work for you?

I was previously running the 2.4.18 kernel... This is the first devel kernel
I have installed since 2.3.x :) I've noticed that according to dmesg, 2.4.x
inits USB MUCH later in the boot sequence than 2.5.7 and 8-pre2 do.

Thanks

The USB core starts up much earlier, yes.
But the OHCI driver should still be initialized at the same place.

What messages do you have in your system log when the machine locks up?

And have you tried the ohci-hcd driver instead of usb-ohci?

Ah, ok.  Haven't heard of this problem before.  The USB core doesn't 
touch any hardware, but only initializes a few things, and adds a filesystem
to the kernel if you've selected it as a option.

Does it also happen if you only build the USB core into the kernel, yet
leave the host controllers and other drivers as modules?

Have you selected any USB drivers to be compiled into the kernel?

Can you send me your .config?

thanks,

Yes, it also happened if I just compiled USB core support in. I would try it
again, but I broke my system upgrading glibc over the weekend(don't ask, I'm
just going to build LFS). I think I have my .config saved, I'll send it when
I get home this evening. When I had core and HC support built into the
kernel, I also had full HID, usb-serial for handspring visors, usb mass
storage, and joystick support. The same configuration has worked flawlessly
on 2.4.x.

Thanks!

	Sorry guys,
	I was late getting home last night. I got my system backup and running to a
degree, and I'll send off my .config when I get home tonight after class.

Thanks
