Description Pekka Pietikäinen 2001-01-02 17:14:32 UTC
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

Comment 1 Bill Nottingham 2001-01-02 17:24:59 UTC
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?

Comment 2 Pekka Pietikäinen 2001-01-02 18:22:17 UTC
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

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.

Comment 3 Trond Eivind Glomsrxd 2001-01-03 11:11:18 UTC
Bill, could you try pulling a new hotplug from sourceforge? URL in package... a
little hard to do from home.

Comment 4 Pekka Pietikäinen 2001-01-05 00:23:43 UTC
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)

Comment 5 Bill Nottingham 2001-01-05 04:51:51 UTC
... which requires a new modutils, which ain't out yet. Fun.

Comment 10 Trond Eivind Glomsrxd 2001-02-02 22:29:43 UTC
I think it should be fixed now, with hotplug 1.9, coming soon to a Rawhide near you.
