(In reply to comment #1) > A patch referencing this bug report has been merged in Linux v3.1-rc1: That's right, thanks for reminding about this bug. The bug appeared to be b43 one, not bcma one. It means Linux 3.0 is not affected and this bug report can be closed as invalid.
Comment 3 Rafał Miłecki 2011-08-08 08:25:25 UTC
To make it clear: 3.0 contains working bcma 3.1 contains working bcma and working b43 For a short moment there was bug in b43 while development for 3.1 merge window. However it was visible only for those brave enough to drop BROKEN from B43_BCMA.
