I've got a Broadcom 4312 LP PHY device that is giving me DMA errors. device = 'BCM4312 802.11b/g LP-PHY' I'm loading the module on boot: if_bwn_load="YES" bwn_v4_lp_ucode="YES" I'm able to connect to an access point for about 5 minutes after startup; however, I then lose connectivity and unable to reconnect without a reboot. Performing an ifconfig wlan0 down/up does not work. Here's a summary of dmesg: bwn0: firmware version (rev 478 patch 104 date 0x8701 time 0x657) bwn0: Fatal DMA error: 0x400 0 0 0 0 0 bwn0: HW reset: DMA error bwn0: firmware version (rev 478 patch 104 date 0x8701 time 0x657) bwn0: Fatal DMA error: 0x400 0 0 0 0 0 bwn0: HW reset: DMA error This just continues to fill up /var/log/messages. Does anybody know if there's a fix for this? Or if there's a even a maintainer at this point? Thanks for the help.
