Hi,

when inserting a PCMCIA bluetooth card, with gentoo-sources-2.6.15-r1 and
pcmciautils-010, the following happens:

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 an attachment (id=78832) [details]
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).
