I am able to use this driver (more or less) for daily use on my netbook, but it is unable survive a suspend/resume cycle without being unloaded and then reloaded again on resume. That actually seems to work quite well. I believe the problem is firmware related: [ 553.355497] wl0: wlc_coreinit: ucode did not self-suspend! [ 554.040495] wl0: wlc_suspend_mac_and_wait: waited 83000 uS and MI_MACSSPNDD is still not on. [ 554.040517] wl0: psmdebug 0x000f8773, phydebug 0x00000000, psm_brc 0x0000 [ 554.154625] wl0: wlc_suspend_mac_and_wait: waited 83000 uS and MI_MACSSPNDD is still not on. [ 554.154647] wl0: psmdebug 0x000f8773, phydebug 0x00000000, psm_brc 0x0000 [ 554.270438] wl0: wlc_suspend_mac_and_wait: waited 83000 uS and MI_MACSSPNDD is still not on. [ 554.270459] wl0: psmdebug 0x000f8773, phydebug 0x00000000, psm_brc 0x0000 [ 554.384569] wl0: wlc_suspend_mac_and_wait: waited 83000 uS and MI_MACSSPNDD is still not on. After the "ucode did not self-suspend", I then get the subsequent two line warnings repeated forever until I reload the driver. Sure, it's probably a firmware issue, but isn't there something the driver can do to kick it into a full reset if it doesn't come back? It's able to do it on module load initially... Jon.
