I upgraded my IBM ThinkPad 240 (Type 2609-31U) from Red Hat 7.0 to
Red Hat 7.1, which uses the 2.4.2 kernel and the kernel PCMCIA drivers.
Before the upgrade, all my CardBus and PCMCIA devices were working fine.
Now the yenta_socket module seems to be causing problems, and none of
the cards work.
Before doing 'modprobe yenta_socket', the PCI stuff looks OK:
% ls -l /proc/bus/pci
total 0
dr-xr-xr-x 2 root root 0 Jun 1 12:52 00
-r--r--r-- 1 root root 0 Jun 1 12:52 devices
% ls /proc/bus/pci/00
00.0 07.0 07.1 07.2 07.3 09.0 0a.0 0b.0 0c.0
and lspci -vvv gives normal-looking output (which I can send if it's
useful).
After the 'modprobe yenta_socket':
% ls -l /proc/bus/pci
total 0
dr-xr-xr-x 2 root root 0 Jun 1 12:44 00
dr-xr-xr-x 2 root root 0 Jun 1 12:44 00
-r--r--r-- 1 root root 0 Jun 1 12:44 devices
Note the two directories with the same name.
% ls -l /proc/bus/pci/00
total 0
-rw-r--r-- 1 root root 0 Jun 1 12:48 00.0
% lspci -vvv
pcilib: Cannot open /proc/bus/pci/00/0c.0
Has anyone seen similar behavior? Is there any way to force
yenta_socket to assign the cardbus to be bus 01 rather than 00?
Thanks!
