This problem has been introduced > between 4.14 and 4.15. Thanks for your report. I just checked the diff between 4.14 and 4.15 for b43 and bcma. It's pretty small and there's no obvious candidate to me that could cause such a regression. This might be a change outside of b43 and bcma that triggered this behavior. Is is possible for you to create a git bisect to find the change that actually broke this? That would be really helpful. --=20 Michael --Sig_/D9eheoKCRTHXOX/1gJI+wXY Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEihRzkKVZOnT2ipsS9TK+HZCNiw4FAlsb7j8ACgkQ9TK+HZCN iw7+5Q//e+wJ+aMXLtwNhgIbDnbP9qsGe7lQK/0J5qdXjcbxdI59HmUb5P640AZv j7yzEIFl/UrzWuj88ZTdAp6BX1Rs+jFyowiiPQGLQyPUh5hfVV6AIpfqf4AiA5T/ GrOIpDcb64hDvET1T3i0bH4rXr0s4glsLnqNcvGpjOeiw6TWS/BJyIqCek7nySCK 5NXMYe4t/01KytKYbVj9fPX7O1J2AuyzHGkm8W9Tej9UsAhe5s+QNA13qRp7yhSQ jWWF3dnqIm1itH04RUKjvDYtbJO49F5fmC24SK79OWMZks+YwLwSCl4A+rD/1+vq gtVAtNWVhLVU8Vm/JbIuHY0EwFtHzuNscsdoezgeadILDzggUbsyl47pQRuz+f0o wOciapHiN5nvUSn0LodBDEkvx6ggvbkfZSiTQri4V9Bpa6OiGKfrSmc2/IHv3PPA sSFRPHeStHuXIGDfKaE5CTbiQ/2GkT8Wmk7lD1OEFRy09Lf1t0N2JqnWxZwDTxRy fL7LErGwqYj56CWR3vXYO/2boWTjDs5WaIBc5R8UDkt7Z/FyU8iNa++9UK5P/0vY fwx/YCGYWORCEpXCL4oZkUVxpixLvJHzDSMWmz6tbap1bHDYow2Hebk1qYSCuwS5 T+SJ3MgQrYLwh23ubbT9sWi/jKWIUxesSOr/Jc+/j/eumN13BXE= =XKHB -----END PGP SIGNATURE----- --Sig_/D9eheoKCRTHXOX/1gJI+wXY--
