kudzu triggers autoload of non-existant cpia.o
Last modified: 2007-04-18 12:30:27 EDT
When booting up b1 kudzu seems to trigger an autoload of cpia.o although no such device exists on the system. This later causes autoloading of bttv.o to fail since there already is a char-major-81 device loaded. This could be a kernel/modutils problem too. Both USB and parallel ports are completely unused. /etc/modules.conf contains alias eth0 tulip alias scsi_hostadapter aic7xxx alias char-major-81 bttv alias usb-controller usb-uhci post-install awe_wave /bin/sfxload /etc/midi/GU11-ROM.SF2 alias sound-slot-0 emu10k1 usb-uhci.c: $Revision: 1.242 $ time 02:59:14 Dec 13 2000 usb-uhci.c: High bandwidth mode enabled usb-uhci.c: USB UHCI at I/O 0xd400, IRQ 9 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected Linux video capture interface: v1.00 V4L-Driver for Vision CPiA based cameras v0.7.4 Parallel port driver for Vision CPiA based cameras v0.7.4 Winbond Super-IO detection, now testing ports 3F0,370,250,4E,2E ...

kudzu doesn't know what a cpia *is*, much less how to load/configure it. I'd guess that it's somehow getting dragged in by something else. *Exactly* when is it getting loaded?
Appears to not be a kudzu problem, problem disappears if nousb is used or modules.usbmap deleted (depmod is run after rc.sysinit configures the USB stuff) Actually it looks like the problem is in /sbin/hotplug, since removing that makes things work again. cpia_usb.o is the first entry in modules.usbmap, so that just might be the reason why it's the one that gets randomly loaded.
Bill, could you try pulling a new hotplug from sourceforge? URL in package... a little hard to do from home.
This is from the 2.4.0 release notes, I'll try to check if this fixes the problem tomorrow (I tried getting a new /sbin/hotplug from CVS and the result was that it loaded _ALL_ USB modules, not just cpia) Matthew Dharm: - USB hotplug fix - specify exactly which fields to match on
... which requires a new modutils, which ain't out yet. Fun.

This defect is considered MUST-FIX for Florence Gold release

I think it should be fixed now, with hotplug 1.9, coming soon to a Rawhide near you.
