Hi, when inserting a PCMCIA bluetooth card, with gentoo-sources-2.6.15-r1 and pcmciautils-010, the following happens: Jan 30 14:52:56 raistmobile cs: pcmcia_socket0: unsupported voltage key.

As a side note: I just tried various other PCMCIA cards, and they do not show any problem. The one causing problems is a 3Com Bluetooth PCMCIA card.
Can you reproduce this with this problem with the latest vanilla-sources (currently sys-kernel/vanilla-sources-2.6.16_rc1)?
Created attachment 78832 [details, diff] Patch which solves the bug The attached patch solves the bug
I posted the patch by Bluez maintainer Marcel Holtman (thanks mate !) which solves the bug like a charm :)
This may be fixed for you, but not the rest of the Gentoo Linux users out there...
I checked with Marcel, who says the patch will go upstream when he finds some time.
Daniel, will this patch go into genpatches?
It already is. I thought you said you saw the commit :)
Thanks for reporting and testing. Fixed in genpatches-2.6.15-9 (gentoo-sources-2.6.15-r6).
