Hi,
I get a kernel panic when starting the hotplug daemon when running 2.5.39, the
config and boot log are attached.
I can get the oops if someone could tell me how.

What hotplug daemon? What is that? Do you mean a call to
/sbin/hotplug?
thanks,

Hi,
Sorry about the last report not the most informative, I'm still getting a
kernel panic with 2.5.40. I think it's my Alcatel USB Speedtouch Modem as it
only panics when I plug it in.
I set up a serial console but I could get the oops I could log in but as soon
as I plugged in the modem it hung.
So I wrote what I could see by hand

In interupt handler - not syncing
With 2.5.39 the call trace was same plus the following
kmem_cach_free
do_exit
sys_exit
syscall_call
and the process was usbmodules
attached is config, lspci and lsmod from 2.5.36 with same config

Are you using the new "in-kernel" driver for this device? Or the
userspace driver? Hm, in looking at your .config, you're not using the
kernel driver, any reason you aren't?
And if you move usbmodules to something else (like usbmodules.orig), it
will not be run by the hotplug code. Does that prevent the oops?
thanks,

I used the kernel driver about 9 months ago but it wasn't reliable, the
userspace driver is brilliantly reliable and also I don't have to patch the
kernel, just looked at 2.5.40 and see it's in the kernel but I have been
using 2.4 till recently but there is still the speedmgmt application which
used to hang the machine on shutdown and also when the link was dropped and
you also need a ATM aware PPP daemon so the userpace driver is IMHO simpler
use.
Moving /usr/sbin/usbmodules to /usr/sbin/usbmodules.orig stops the kernel
panic, I get the following on boot
Starting hotplug subsystem: usb** can't synthesize root hub events.
Thanks
