Subject: [2.5.44] 8250_cs does not work.

Hello,

Since I've started to test the 2.5 series, I've noticed that 8250_cs doesn't
really work - it doesn't detect my pcmcia card (psion global gold card).

I had a patch for 2.5.40 from Russell King that fixed it, but I can't get it
to apply to 2.5.44, and well - out of the box it still doesn't work.

Is there any plan to get that fix in the kernel?

Thanks!

DK

The fix went in, so something else must have broken it. There were some
changes to the PCMCIA layer resource handling. Please supply:

1. kernel messages
2. cardmgr-related messages from /var/log/messages
3. /proc/ioports
4. /proc/tty/driver/serial

Ah. Looks like I owe you an apology.

I hadn't rebooted after symlinking 8250_cs.o to serial_cs.o. I did a depmod
-a, and then manually loaded the module - this caused it to not detect my
serial pcmcia card.

Rebooting and getting it loaded through cardmgr does work. Odd. Anyway, I'm
happy :oP
