I'm running PCLOS .92 with kernel 2.6.12. I've tried the new acp modem mwave-2.0 binary RPM and also compiling it - same result. It happens when the module loads. The module remains loaded, but the driver can't initialize. What is this problem? There's no 8250.c file in the kernel source, so I can't see the problematical line.

Here is the dump from dmesg.
