USB stops working with any of 2.4.22-pre's after 2.4.21

On any of the 2.4.22-pre's, after a bit of time, my USB mouse stops responding. It is using the usb-ohci driver. 2.4.22-pre1 included the new ACPI base. Even before this ACPI was merged into mainstream, I had tried patching the system with the newer ACPI on 2.4.21-pre, and rc's and I also ran into the same problem that I am now getting with 2.4.22-pre's. I'm suspecting the new ACPI is behind this. Stopping gpm and removing usb-ohci and then reloading it doesn't seem to get it working again. A reboot does the trick. Strange though is that the one USB 2.0 device I have plugged in still continues to work (at least for a while as I normally reboot when the problem arises) when I start having the problems with USB mouse. But then, it uses the ehci-hcd driver.

Some hardware info. I'm using a nForce2 board with an ATI Radeon video card.

I am not subscribed to LKML, but I do check the archives regularly.

Hmm, forgot to mention that I've tried 2.4.22-pre1, pre2, pre3, and pre4. All incur this problem.

Hm, looks like bad things are happening with your interrupts.

Do you need acpi to run this box? What happens if you disable it?

As it looks like networking is also in trouble, I don't think this is a USB specific problem for you.

Good luck,

greg k-h

I have a couple of nits with usb here too.

kernel is 2.4.22-pre3

dmesg shows this for a radio shack/Prolific 2303 usb-seriel convertor:

And my ability to use it, while never great due to config problems on the other end of the cable, seems now to have gone away. There has also been some pretty heavy lightning activity in the area, during which time it may have been hooked up, and something blown from the EMP of a nearby strike. I usually leave it unplugged on the seriel side because of that.

Does this look normal? ISTR it used to ID itself all the time, not just in dmesg.

What does /proc/bus/usb/devices show for this device?

And yes, there are two printers attached. The 820 is for sale. And, sort of as an afterthought, lemme toss in that the Belkin Bulldog UPS monitor soft, runs on a real serial port, /dev/ttyS1, hasn't worked since about 2.4.18 or so. Somewhere about that time anyway. I've yelled at Belkin since it was compiled on a RH5.2 system and they've refused to update their proprietary drivers. Or to release the API even if I'd have signed an NDA. NDI why.

Looks ok, the device probably just doesn't have any string descriptors (or any valid ones at least.)

It should not affect the operation of the device, right?

It must be time for me to see if I can find enough 9 to 25 pin adaptors and stick an led sniffer in the line then, because I cannot talk to the trs80 Color Computer on the other end of the cable.

I'll be back on this if I find anything interesting. Of more interest is the fact that the belkin bulldog kits upsd cannot talk to /dev/ttyS1 although it is picking up data from the port. It outputs on localhost:2710 but its only the keep-alive chatter from the ups. Apparently no commands can be sent to the ups.

This however, is a seriel port problem, not usb. I was sort of hoping there might be a common thread to the failures. :)

Sorry if this is a duplicate...I received an error bounce

ACPI isn't absolutely needed, but it comes in handy for issuing a shutdown.
Though I suppose I can use apm to do this as well.

On a uni-processor system, isn't the ACPI tables used to setup the IO-APIC bits to have PCI IRQ routing so that I have more than 16 interrupts? This was another reason I had enabled ACPI.

When I do get those interrupt problems, my network still continues to function while the USB mouse fails. I do agree it's not USB specific. It's more tied in to ACPI/(IO-)APIC.

When I get back home, I'll try booting it with acpi=off on pre4 and see how it goes.

acpi=off on 2.4.22-pre4 for the last 4 hours and haven't run into the interrupt/usb problems. Normally the problems arise not too soon into the boot up, forcing me to boot up 2.4.21 if I ever wanted to log on remotely. Looks like all my problems are being caused by the newer ACPI code base merged since pre1.
