1 Hi,
2
3 Has anyone managed to get BCM4312, 802.11b/g (pcie) Device: pci
4 0x4315, going with the b43 module?

14 I've unmasked and am using the latest firmware in portage and the b43
15 module from the gentoo-sources-2.6.32-r7 kernel. The card comes up,
16 then authenticates and tries to get an IP address, but in less than a
17 second after it gets an IP address it crashes with these recurring
18 messages above.
19
20 Is there a fix, or shall I go for the wl module by Broadcom or even
21 give up and go for the ndiswrapper solution?
