I have a Plustek 9636T parallel port scanner. Has been faithfully working for me for years up through Fedora 8. It has a kernel driver that I build and install every time the kernel changes.
I finally bit the bullet and did a new install of Fedora 12 to get up to date. But now when I try to build my kernel driver and install it, I get this fatal error on the modprobe:
FATAL: Error inserting pt_drv (/lib/modules/220.127.116.11-174.2.3.fc12.i686.PAE/kernel/drivers/parport/pt_drv.ko): Unknown symbol in module, or unknown parameter (see dmesg)
Examining dmesg shows: Unknown symbol proc_root
. I can't find that message anywhere on a Google search.
Anyone have a clue to help me understand this problem? Thanks!
