oops in uhci.c running 2.4.2-ac28

oops in uhci.c running 2.4.2-ac28

[Ketil Froyn]

Hi.

While running kernel 2.4.2-ac28, I switched on spinlock debugging and
verbose BUG() reporting (I always use sysrq). Anyway, while running this I
got an oops after about 2 or 3 minutes running, several times, exact same
place each time, which I traced back to rh_int_timer_do(). This was in
uhci.c (I used CONFIG_USB_UHCI_ALT).

The oops was at [<c01e4d24>], and rh_int_timer_do starts at [<c01e4cac>]
(I'd calculate the offset in the function, but it's too late at night). I
recompiled with usb-uhci.c instead (CONFIG_USB_UHCI), and now I don't get
the oops any more. Using nm vmlinux, I got this stack:

rh_int_timer_do
timer_bh
bh_action
tasklet_hi_action
gcc_compiled. (?)
do_IRQ
default_idle

If more info is needed, I'll be glad to reproduce the bug and copy the
oops here.

Also, the reason I started all this debugging was that I have a freecom
usb CD-RW that stops when I try to access it (the process is in
uninterruptible sleep and never comes out) when I access some files on
some CDs. If anyone knows about this, I'd appreciate any tips. Also, if
anyone has the technical specs on it, I'd even be willing to (try to) look
at it to see if I can spot something with the freecom code... haven't
found anything on www.freecom.com yet.

I am behind usb-uhci for a reason. Alan bounced your report
to me but I do not see a case for action...

Let me show what I got with the 2.4.2 kernel with USB support enabled.

Mar 19 14:10:00 Eng99 kernel: uhci: host controller halted. very bad
Mar 19 14:10:31 Eng99 last message repeated 108 times
Mar 19 14:11:37 Eng99 last message repeated 93 times
Mar 19 14:12:39 Eng99 last message repeated 87 times
Mar 19 14:13:40 Eng99 last message repeated 20 times
Mar 19 14:14:45 Eng99 last message repeated 42 times
Mar 19 14:15:46 Eng99 last message repeated 47 times
Mar 19 14:16:47 Eng99 last message repeated 127 times
Mar 19 14:17:50 Eng99 last message repeated 7074 times
Mar 19 14:18:51 Eng99 last message repeated 3342 times
Mar 19 14:19:52 Eng99 last message repeated 10948 times
Mar 19 14:20:00 Eng99 last message repeated 15
times                                                                    

This happens after simply fiddling around with ethernet settings (it's a
PCI ethernet card).  In fact, my syslog is FULL of these messages... my
syslog was 3x larger than usual.  The console is just about unusable
because of all the spam.

Something seems terribly wrong with the uhci driver... I've disabled it
on my system and it's fine now (I don't need USB).

My system:
Slot 1 P3-850
VIA chipset MB (not sure of exact chipset, can find out if needed)

Do you get the same messages with the usb-uhci driver?

Some of the VIA chipsets have port aliasing problems supposedely. This
may cause your controller to go insane like you've described.

Don't think I tried that one.

That could explain the issue.  Fortunately, I don't need USB so I can
avoid the spam, I just thought someone might like to hear about it.

P.S.  Sorry for responding directly to you, Johannes.

What do you mean by "behind".

Have you tried the latest patches for uhci.c?
