Hi Vitaly,

Sounds well known ;-)

You may search deeper :-)
But my research didn't produce a solution, so best chance you have
is found some people which would feel with you :D

Maybe you apply the attached patch and reply with the "enhanced" debug
messages.

And make sure to have

hw.cbb.debug=1
hw.cardbus.debug=1
hw.cardbus.cis_debug=1
hw.pccard.debug=1
hw.pccard.cis_debug=1

Maybe some guy with a little more experience than me may give you a
workaround
until a patch is existing.

Best regards,
Jens
