Laptop doesn't shutdown properly: CardBus + USB combo drive

[aletroux]

I have a Compal notebook dual-booting Windows 2000 Pro and Debian (based on the usual Knoppix-to-HD conversion, using knx-hdinstall). When running Knoppix from the CD (on my laptop's internal CDROM), I don't have the following problem, so I assume it CAN be fixed. Caveat: I'm a Linux newbie; this is my very first installation.

My laptop didn't come with any USB2 ports, so when I purchased a USB Combo drive (a Philips Jackrabbit JR32RWDV), I also bought a Sitecom CardBus USB 2.0 PC Card, with two USB2 ports on it. This is what lspci -v has to say about my USB and CardBus situation (apologies; it is VERY verbose! ) . (Oh yeah, and I have two CardBus slots, but only one card installed, and a USB mouse plugged directly into the laptop (not through the card))

Now everything works just fine (mounting and all), but when I logout/shutdown Linux, instead of powering off like it does when I run the Knoppix CD, it just hangs. I haven't copied the last message I saw, but the most prominent message is something like 'EHCI takeover failed!' (exclamation mark included, would you believe). When I remove the USB drive, everything boots down normally again (with and without the card).

Can something be done? I am a bit uneasy about powering off manually every time. So far I haven't had any damage, but who knows what's supposed to happen after this?

Kind regards

Ok, I've had time to boot and write down messages displayed on the screen while shutting down:

Ok, this is all Greek to me...

I have the same prob... i never had it under standard debian or redhat on this laptop. my only guess is that it's because the system shuts down pcmcia and THEN usb, and panics when it caan't unmount thhe already unmounted PCMCIA usb ports. This is on a toshiba 2410, by the way. I looked in the shutdown scripts but didn't see anything blindingly obvious to cchange (but that could be just me, i'm no expert, just a user with a detectproblem-respond approach to configurattion)

I'll try mucking around in the kernel config and see if i ccan get anywhere...

(yes, i'm about to fix this sstupid kkeyyboardd bouncee prrobleem!! just haave to rebooot!)

I'm at work, so I didn't bring my pcmcia and external usb stuff... so I don't know if this'll work, but it looks promising.

I had a squiz at linux-usb.org/usb2.html, and it says that before the 2.5.something kernels, you had ("have") to manually remove certain modules in order for the shutdown to effectuate cleanly. I can't try this until this evening or maybe this weekend, but it says to do this - as root, of course -

rmmod ehci-hcd
rmmod ohci-hcd
(then shutdown)

Or you can upgrade to something past 2.5.29. Maybe you could remove other modules related to usb, like usb-uhci or even usbcore. Heck, i'd try it.

I'll look forward to trying it out myself..

Should have thought of that... of course. Haven't tried it out yet (I'm moving house this weekend. Great.), but it might work. Do you think it's possible to change the shutdown order (in scripts, I suppose. Where?) so that it shuts down all USB stuff BEFORE the PCMCIA?

Anyway, got myself a couple of pristine kernel sources. Might as well build my own, since I need to get my Winmodem to work too...
