Version-Release number of selected component (if applicable):

Additional info:

I have been starting the cpia module
at boot in rc.local and the calling webcam for 
a live parallel port camera on my webpage
my server is a pII smp dell power edge 
this has been working fine untill the newest kernel upgrade
after the upgrade and reboot the system froze before
login & after a recover boot & remoing from rc.local
it boots. I have tried modrpobe cpia after login 
and it freezes the system up 100%

Comment 1 Richard Moss 2002-10-30 11:44:26 EST

only on smp kernel,I have tesed with non-smp and no problem
I have also gone up to 2.4.19 kernel and hard compiled in the cpia
with the same effect ..deadlock but only in smp

Comment 2 Richard Moss 2002-12-06 11:59:43 EST

OK so..
I have compiled in (and out) the parallel port with 2.4.20
I have used the src from 1.2.2
I still get the same deadlock 
I do get messages in var now that show the modules
going in & the moment it adds in the cpia_pp
it freezes, when I just add in videodev & cpia (sans
cpia_pp)
it won't freeze (but of couse there is still no camera)
I have made a non-smp kernel and it works again
in reading postings I found a reference to the parport
driver in the kernel & made the mods to the src as well
with the same effects as before..
suggestions ? 
what should the perms in /dev be on video ?
