Hi, 

It seems the problem reported by Silla Rizzoli is still present in 2.6.x
and 2.4.25 (both include the voltage interrogation patch by rmk).

Daniel Ritz made some efforts to fix it, but did not seem to get it right. 

Just a reminder.

Maybe we should add it to the bugzilla?

The laptop is an IBM R40 2681-BDG. That means P4 1.8 GHz (non-Centrino), with 
chipset 845.


I own two pc cards, a Cisco Aironet 350 (AIR-PCM352) and a Option Globetrotter 
GSM/GPRS card, driven using serial_cs.

The cards always get correctly recognized in they are already inserted at boot 
time, but rarely if plug them in when my Gentoo has finished booting. To make 
them work a cardctl insert 0 (I only have one socket) usually helps, 
sometimes I have to unload/reload the pcmcia modules, and very very rarely a 
reboot is needed; this happens with 2.6.x and 2.4.25. The two PC Cards behave 
the same, maybe the Cisco one is a bit more picky.

You'll find a complete lspci here:

The kernel config for 2.6.3 here:
http://www.communicationvalley.it/2.6.3-oldradeon.cfg

The kernel config for 2.4.25 here:
http://www.communicationvalley.it/2.4.25.config

I only used pcmcia-cs on a distant past, but I'm downloading them now, I'll 
let you know how they work very soon.

Thanks,
