It looks like recent HEAD seems to fail intermittently here on my home network. It will recover, but urtwn(4) seems to lose an ack or something on txmit. turning on debug, yields this message during the hang event. hw.usb.urtwn.debug: 1 Oct 28 12:34:58 bruno kernel: _urtwn_getbuf: _urtwn_getbuf: out of xmit buffers Oct 28 12:34:58 bruno kernel: urtwn_getbuf: urtwn_getbuf: stop queue Oct 28 12:34:58 bruno kernel: _urtwn_getbuf: _urtwn_getbuf: out of xmit buffers Oct 28 12:34:58 bruno kernel: urtwn_getbuf: urtwn_getbuf: stop queue Additionally, I get the following at module load time: urtwn0: <vendor 0x0bda product 0x8176, class 0/0, rev 2.00/2.00, addr 1> on usbus0 urtwn0: could not read efuse byte at address 0x10 urtwn0: could not read efuse byte at address 0x18
