usb inboard Abit BE6, ADSL modem Speedtouch usb.
I used to use satisfactorily usb-uhci-hcd before 2.5.25, switching to
uhci-hcd halts the adsl modem after a few minutes with this message:
kernel: uhci-hcd.c: c000: host controller process error. something bad
happened
kernel: uhci-hcd.c: c000: host controller halted. very bad
2.5.24 is not happy too with uhci-hcd.
What should I look at ?
Pierre

Is this the usbfs userspace ASDL driver? Or the kernel driver?

I'd suggest asking the authors of the driver about this.
Good luck,

Is your kernel preemptive?

The driver is made of a kernel module speedtch.o (built outside of the tree) and of userspace modem firmware loader and management daemon speedmgt.

In answer to the question, "is your kernel preemptive":

Well, the original module code contains several races. I spent
some time cleaning these up (because it would sometimes oops
on a preemptive system), until I cracked and went over to the user
space driver... But maybe you are not using the original code?
All the best,
Duncan.

The driver is OK with usb-uhci-hcd up to 2.5.24, you might as well suggest to un-plug it...

I also get the "very bad" message when booting 2.5.25 and 2.5.26, even
if no usb devices are connected. From dmesg:

This happens both with preemtible and non-preemtible kernels. I can
still use a Freecom usb cdrw drive though, so maybe this is not a
problem, even though the message indicates that it is.
I also have a performance problem with the uhci-hcd driver. When
writing data to a CDRW in packet writing mode, usb_stor_freecom_reset
is called quite often, see logs below. This happens in both 2.5.25 and
2.5.26. I tested with the usb-uhci-hcd driver in 2.5.25 (edited the
Makefile) just to rule out kernel changes and other usb changes, but
that driver didn't have this problem. I saw one or two freecom reset
messages though, so it's possible that the new driver just makes an
old problem much more frequent.
