Does the attached patch help?

Subject: brcm80211: smac: fix endless retry of A-MPDU transmissions

commit 5e379203c7788b7af01150bfadbc74d2797a2ef4 upstream.

The A-MPDU code checked against a retry limit, but it was using
the wrong variable to do so. This patch fixes this to assure
proper retry mechanism.

This problem had a side-effect causing the mac80211 flush callback
to remain waiting forever as well. That side effect has been fixed
by commit by Stanislaw Gruszka:

commit f96b08a7e6f69c0f0a576554df3df5b1b519c479

Patch looks promising but following above instructions I failed to build
patched 686-pae flavour i386 kernel using amd64 system (and not possible to build on
target machine because lack of space).

Easiest way is probably to set up a 32-bit chroot.

Here are some alternative instructions.

0. prerequisites:

apt-get install git build-essential gcc-multilib

1. get a copy of the kernel history, if you don't already have it:

git clone
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

2. fetch point releases:

cd linux
git remote add stable
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
git fetch stable

3. configure, build, test:

git checkout stable/linux-3.2.y
ssh target-system 'cat /boot/config-$(uname -r)' >.config
scripts/config --disable DEBUG_INFO
make ARCH=i386; # optionally with -j<num> for parallel build
make ARCH=i386 deb-pkg
scp ../<name of package> target-system:
ssh root@target-system dpkg -i <package>
ssh root@target-system reboot

Hopefully it reproduces the bug. So:

4. try the patch:

git am -3sc /path/to/patch
make ARCH=i386; # maybe with -j4
scp ../<name of package> target-system:
ssh root@target-system dpkg -i <package>
ssh root@target-system reboot

Hope that helps,
Jonathan

Gah --- I left out a line here. I should have said the following:

git am -3sc /path/to/patch
make deb-pkg ARCH=i386; # maybe with -j4
scp ../<name of package> target-system:

Default Bug#672891: brcmsmac wireless brcms_c_wait_for_tx_completion warning

Again failure
It seems that brcmsmac is enabled by some Debian patch, that don't get
enabled when building from upstream 3.2.x git tree. It would make sense
to offer current Debian kernel git tree also.
That kernel has this in dmesg:
[ 4.468517] b43-phy0: Broadcom 4313 WLAN found (core revision 24)
[ 4.469335] b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 10, Type 8,
Revision 1)
[ 4.469389] b43: probe of bcma0:0 failed with error -95
Attached is diff between official Debian config and custom config.

There is [1], but it doesn't get updated as frequently.

Oh, right. The relevant Debian-specific change is

* Enable BCMA as module, BCMA_HOST_PCI and B43_BCMA (Closes: #649567)
but limit these to devices not supported by brcmsmac

To get brcmsmac, disable BCMA:

make nconfig
Device Drivers → Broadcom specific AMBA → BCMA support: N
Device Drivers → Network device support → Wireless LAN →
Broadcom IEEE802.11n PCIe SoftMAC WLAN driver: M

Or from the command line:

scripts/config --disable BCMA
scripts/config --module BRCMSMAC

Sorry for the fuss.

Sincerely,
Jonathan
