insmod inserts the module. but lsmod does not list it. using Plx load module utility.
Hi,
I bought a PLX 9054 bridge based PCI card for some serial communication, (MESA 5i21). I downloaded the Linux PLX SDK, built the drivers for the PLX chip.
PLX has given a module load utility plx_load (attached).
When I try to load the module, the insmod returns a success. But the same module is not listed by lsmod. The Plx_load utility verifies the insertion of the module. The output of the Plx_load is also attached.
I have not encountered such a problem before.
by the way I am using the RHEL 6.4 kernel version 2.6.32.358
The Plx_load is below...
