Hello,
I thought this error may be of interest to someone on this list. My
computer called it a kernel BUG. I wasn't sure how much information was
needed, so I played it say and filled out the bug reporting form to the
best of my ability. If you are only interested in seeing the error
message, go all the way to the bottom of the message. It's the last
thing in this mail.
I'm not subscribed to this list, please copy me on any replies,
thoughts, suggestions. Thank you.
Franco
----- bug report -----
[1.] One line summary of the problem:
A bug in usb-ohci.c that causes my laptop (Presario 2800) to freeze.
[2.] Full description of the problem/report:
The output from my machine is included all the way at the bottom of
this message, section 7.7.
The system is a Compaq Preasrio 2800 laptop. If I hit the FN+F2 key
combination, to activate the stupid wireless lan multiport module,
the system freezes. Sometimes it must be hit twice in succession, to
get the bug to freeze the system, but most of the time once will do.
I get a bug report, but I don't know what it means. I'd like to get
some information about this. In particular, how to fix it. :-)
[3.] Keywords (i.e., modules, networking, kernel):
kernel, modules, networking, wireless lan

I have noticed this problem in 2.5.39 except it occurs with the module
uhci-hcd. I can work around the problem by using the 'nousb' feature that
the redhat rc scripts recognize. I then load the modules by hand with
pcmcia initialization first (pcmcia_core->yenta_socket->ds) then usb
ohci-hcd, uhci-hcd, then ehci-hcd last. Then I can go ahead and load the
hid and usb-storage drivers also.

Hmm, if I look at that line in the 2.4.20-pre7 kernel, I see:
/* likely some interface's driver has a refcount bug */
err ("bus %s devnum %d deletion in interrupt",
ohci->ohci_dev->slot_name, usb_dev->devnum);
BUG ();
That BUG() has been an "oops now predictably, or oops later randomly"
situation, and EVERY (!!!) time it's been an issue, the problem has
been traced to exactly what that comment says: some interface's
driver has bogus disconnect() processing, and is not cleaning up. (*)
It's likely the problem is in the driver for one of your USB devices.
Given what I saw, it sure looks like "prism2_usb" is the problem.
And from what I saw last time I looked at that driver, I can VERY
easily believe that ... in fact I think I've seen similar reports
show up before, that's why I took a look at it. The prism2_usb folk
need to make sure their disconnect() routine (a) prevents all further
driver requests to that device, (b) unlinks all urbs it submitted,
and (c) waits for them to finish unlinking.

(*) Maybe a better response would be to just leak memory, but
that's how the ohci driver evolved ... it took a long time
to establish that the oopsing was really caused by bogus
disconnect() processing in the layered usb device handling.

No you haven't. It doesn't have a file of that name, so you
didn't see such a BUG(). And I don't know about you, but my
copy of 2.5.39 has no BUG() anywhere in the ohci-hcd driver,
so it'd be hard seeing _any_ BUG() coming from there.
You might be hitting a different BUG(), but in that case you
would need to get your bug reports straight.

Actually there is a file of that name 'uhci-hcd' in the 2.5.39 source,
which I was talking about. I was also talking about the uhci-hcd driver
in the 2.5.39 source which doesn't necessarily have to have a BUG in that
code. Here is my call trace:
uhci-irq [uchi-hcd]
usb_hcd_irq_Rfba60562 [usbcore]
handle_IRQ_event
do_IRQ
common_interrupt
page_remove_rmap
zap_pke_range
zap_pmd_range
unmap_page_range
exit_mmap
mmput
exec_mmap
flush_old_exec
load_elf_binary
load_elf_binary
search_binary_handler
do_execve
sys_execve
syscall_call
Code: 83 7b 18 8d 73 04 74 38 c7 04 24 80 f8 88 d0 89 5c 24 04
<0> Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing...
I am apparently hitting a different bug, but it inevitably comes from
the uhci-hcd driver (according to the panic).

As I said: you're not seeing "this problem". And it's not a BUG().
So now we agree ... ;-)
You might try sending the full oops report to the maintainer
of that driver, or at least to the linux-usb-devel list.
(The 2.5.39 code gives more info than you snipped...) So far
as I know, this problem has not been reported there.

Its so nice how these things work out :).
Thanks for your time and help,
