Hi,
I'm using the b43 driver to connect to a WPA2 encrypted WLAN. When I
enable the kernel option CONFIG_DEBUG_SLAB my connection breaks.
wpa_supplicant can establish the connection and I can make pings or DNS
queries, but downloading a file kills the connection. The kernel log
includes these lines:

But in the case of "git revert", it should be an ancestor (or the user
is just insane, in which case it doesn't matter - insane people can do
insane things)
