I have a bcm4311 chipset; it is identified in `lspci -vnn` as:
01:00.0 Network controller [0280]: Broadcom Corporation BCM4311
802.11a/b/g [14e4:4312] (rev 01)
Without compiling the kernel with some of BCMA disabled, I cannot make
my card work at a decent speed.
This is in Linux Kernel 3.13, but I have had this problem with other
recent kernel versions.
My hardware is a late 2006, Intel Core 2 Duo iMac, and the linux
distro is Mint 16.
The problem is that both SSB and BCMA are loading to support the b43
module, where I only want SSB to load. I had this issue in 3.11, and
my custom build of 3.13 worked, but I don't see any changes to b43 or
BCMA that would effect this. I think that it was my tweaking of the
compile options for BCMA fixed this, but in any case
I believe that the SSB and BCMA modules are interfering with each
other, killing my network speed seemingly at random.
I think it's because my card (*'0x4312') is being recognized in bcma
as a supported bcm4312 or 4313 chipset, when it actually can indicate
a 4311 chipset, which, as far as i know, is not supported by these, or
brcmsmac. I have to admit I am not clear on the differences between
these chipsets, but I do know the 4312 is a PHY device, and as far as
I know, the 4313 is an upgraded 4311.
Attached are the `lspci` and `lsmod` outputs for when the 3.13 kernel
is loaded and when the 3.11 kernel is loaded. I believe that without
tweaking my compile settings, my system would still be behaving badly.
The 3.13 kernel works, and lsmod shows that bcma is not loaded. 3.11
doesn't and shows it as loaded. I am having a hard time finding my
unmodified .config file for the kernel, but i have an intermediate
step's config file which also exhibited the problems. The `lsmod` and
`lspci` files also contain the outputs of `uname --all` so you can see
details of the kernel being used when I performed each test.
I apologize if I am giving too much information, but I have never
reported a bug in the Linux Kernel before. I hope I did alright :)
