[PATCH] Make ThinkPad T42s PCMCIA always work
Last modified: 2015-01-04 17:10:09 EST
Description of problem:
In May of 2004, IBM released the new "42 and 42p" models of their very
popular T line. Some (maybe just the ones with 1.8 and 2.0 Ghz CPUs)
or all of the T42s have a new Cardbus bridge that isn't properly
recongized by yenta. The problem is that card inserts are not detected.
The odd thing is that without the following patch, card inserts will
be detected as long as another network interface (such as the onboard
NIC) is up.
With the patch everything is golden, and card inserts are always detected.
The patch is a 2 liner, presumably Russell King has it in his queue,
but who knows when it will makes it into the Linus kernel, and it
might not happen until after FC3 is released.
Please add to the rawhide kernel so that users of T42s everywhere will
have 100% working PCMCIA with FC3.

Patch to add proper PCMCIA support for Thinkpad T42s
While this seems like an obviously good and easy change, it would
*really* help if you could please help to push it for upstream
inclusion. It is already too late for FC3T3 but maybe we can get it
into FC3 final.
Linus just releaesed 2.6.9-rc3. It has the fix.
(Bookmarkable bkbits link)
Guess this can be closed now since the fix was reportedly fixed in
2.6.9-rc3', current devel kernel have 2.6.9-rc4.
