[hcflinux] Kernel oops upon initialisation

Mon Mar 22 16:46:28 EST 2004

G'day!

I'm having a few issues with the latest hcfusb drivers..

I have a 600mhz G3 (white) ibook.
I've made myself a shell script to dial, which basically does a:

sudo sh -c "
        cp /etc/hcfusb/backup/current.inf /etc/hcfusb;
        modprobe hcfusbserial;
        sleep 5;
        pon;
        "
(As /etc/hcfusb/current.inf is corrupted as soon as the drivers are
loaded, I have to restore a backup every time I dial... =) No biggie)
This can work quite happily sometimes, but initialisation of the hcfusb
driver causes a kernel oops if the computer has been put to sleep
previously.  If I reboot, then initialise the drivers and dial, it works
perfectly.

The oops (Actually, there are two...):

recent than /lib/modules/2.4.20-ben10/modules.dep

May 17 15:35:45 localhost pppd[1957]: Connect script failed

I attempted an 'hcfusbstop', then got a 'device busy' type error... I
tried a 'poff', then recieved a kernel panic.. All I got down was "TASK:
'swapper'".
This happened a couple of times before, and I've attempted to reboot the
computer immediately, and recieved a kernel panic upon halt (before the
halt process completed)...
After the system restarts, my system clock is always set to Fri, Jan 1,
13:43 1904, or thereabouts.

I had a look through the system log to see if there were any problems
with sleep/restore, but didn't find much, apart from some
Usb*CompletionRoutine errors, which may or may not be relevant:

I'm running kernel 2.4.20-ben10 with Debian unstable.  I'm using the
hcfusbmodem-0.99lnxtbeta03042703ppc drivers.

Thanks in advance!
