[gentoo-user] Dreaded broadcom BCM4312 wireless card causes DMA failures and crashes

[Mick]

Hi,

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

b43-phy0 ERROR: Fatal DMA error: 0x00000400, 0x00000000, 0x00000000,
0x00000000, 0x00000000, 0x00000000
b43-phy0: Controller RESET (DMA error) ...
b43-phy0: Loading firmware version 410.2160 (2007-05-26 15:32:10)
b43-phy0: Controller restarted
b43-phy0 ERROR: Fatal DMA error: 0x00000400, 0x00000000, 0x00000000,
0x00000000, 0x00000000, 0x00000000

I've unmasked and am using the latest firmware in portage and the b43
module from the gentoo-sources-2.6.32-r7 kernel.  The card comes up,
then authenticates and tries to get an IP address, but in less than a
second after it gets an IP address it crashes with these recurring
messages above.

Is there a fix, or shall I go for the wl module by Broadcom or even
give up and go for the ndiswrapper solution?

Posted too early perhaps.  There seems to be a patch coming for the
2.6.33 kernels.  Will have to wait I guess.

im guessing here. maybe you have old firmware. did you get the "old
firmware" warning in your kernel messages when you loaded the module?

No.  It was a kernel problem.  The new 2.6.34-gentoo-r1 works fine.
