Please file a bug with Red Hat.
May be I'm wrong, but I've opened a service request (600548) and I
expected to be part of the internal "escalation" to open a bug.
That's even better. It'll get to me when I get from vacation,
then I'll ask what you actually did to produce the oops
(you forgot to mention it in the original report).
You are for sure referring to my post on linux-usb-devel (because in the
service request there is a ton of thing...)
Anyway, to produce the panics I follow this procedure:
1) Install a USB modem (Multitech and Zyxel, at the moment)
2) Installa hylafax (an open source fax server)
3) Configure the modem to send/receive faxes
4) Send a fax to a busy line
5) Wait
Hylafax, after first failure, tries to send the fax in about 4 minutes.
At the third (or at maximum the fourth tentative), I get a kernel panic.
For what I can "see", when the timeout of re-send the fax comes, the
process that send faxes requests to lock the device and from time to
time the request raises the panic.
Just to say, if the line is free and the call do happen, it works
normally (and at the moment I never experienced kernel panic unless
after a failed call). I can add that no panic come from received calls.
In the meantime that you are on vacation, may you (or some one else in
the list) lend me a hint on how to compile the redhat kernel with debug
information? (So that I can use the crash utility with the vmcores?)
I've tried to put -g in the CFLAGS but nothing happens. (tried also
CFLAGS_KERNEL).
I suspect I have to switch something in the menuconfig (perhaps kernel
debugging/frame pointers?) and do some other additional tricks.
Please. Help me!
The oops itself is on the interrupt context, so it's not
enough to figure it out.
