portable, ATEN USB 2.0 PC-Card crashes RH8 during shutdown

by **Ulf Samuelsson** » Wed, 18 Aug 2004 19:16:37 GMT

Have an ATEN USB 2.0 PC-Card in a Dell Latitude C800 running RH8.0
This works OK with my USB Memory stick, mouse, keyboard
but when I shut down the system, it freezes halfway, so I have to
turn power off.

When I reboot I then of course have to fsck the system...

I think but have not tried, that I can fix the problem by doing

# rmmod ehci-hcd

before shutting down.
Would like to automate this so the question is:

How can I automatically run a script when I shut down the system?

Look for anything that runs in runlevels 0 and 6.

Also, I've had problems with that EHCI module myself, so I wouldn't
even attempt to load it.

Craft a script similar to what is in /etc/init.d then run chkconfig and
tell it to run that on initlevel 6 I think.

Nope. In SysV init setups (used by every distro except Gentoo and
Slackware) runlevel (not "initlevel") 6 is for "reboot". Runlevel 0 is
for "halt". The easiest/best thing to do may be to modify the "local"
script (/etc/init.d/rc.local?) so that it does "rmmod ehci_hcd" when
called with argument "stop". Add the S99 symlink to this script to
directories /etc/init.d/rc6.d and /etc/init.d/rc0.d , or use chkconfig
to do that.

Note that if you have a USB2 device plugged in and mounted, and you try
to shut down or reboot, the rmmod will fail and your system will hang
when halt -p is executed. There's no real way around that. Maybe move
the rmmod somewhere before S99, so that the umount -a is done before
the rmmod. HTH,
