I have a IBM ThinkPad 770X with a TI1251A.
Now since I upgraded to RedHat 6.2 and then compiled my own kernel (2.2.14, 2.2.15 or 2.2.16pre6) and compile the PCMCIA package (3.1.14 or 3.1.15) and load the pcmcia subsystem the system effectively hangs. I can still when I'm in textmode switch consoles and try to login but it looks like that any atempt to access the harddisk hangs.
I compile the PCMCIA package with isa pnp and cardbus support, as I have a 10/100Mb cardbus card. This always used to work in the past without problems.
With RH 6.2 the only way for me to have PCMCIA working at current is to use the standard pre-compiled kernel and pcmcia package that comes with redhat. And that is giving me a lot of problems as the default APM options are wrong for this machine.
The PCMCIA version (3.1.8) that RedHat supplies with 6.2 prints the following:
