yenta_socket/PCMCIA problems.Re: [ltp] FYI - Linuxcare T30 certification now available.

[David Margrave]

Hello,

I had similar problems with newer kernels.  It turned out to be that I had
to exclude one of the built-in IRQs for the serial port.  Then card
insertions worked fine.  It wasn't even the same interrupt in question,
but just the fact that it wasn't excluded caused all kinds of havoc.
Email me and I can dig up the exact information this evening.

Dave
