Just saw this again:

1. Connection got lost (probably due to the peer, so not the driver's
   fault)
2. Lots of
   kernel: (ESSID of Access Point)
   kernel: NETDEV WATCHDOG: wlan0: transmit timed out
   kernel: wlan0: Tx timed out.
   kernel: NETDEV WATCHDOG: wlan0: transmit timed out
   kernel: wlan0: Tx timed out.
3. No more activity in the driver,
   (iwpriv wlan0 cnt 1; dmesg) says
   regWaitRCompCnt = 00017770, regWaitWCompCnt= 00011806
   regRWCompCnt    = 00029575, regUnCompCnt   = 00000024
   regWaitRspCnt   = 00017769, regRspCompCnt  = 00017745
   regRdSleepCnt   = 00004045, regRspCompCnt  = 00017745
   (full output see below) so we're probably stuck in
   wait_event(macp->regSet_wait...) somewhere in zd1211.c as
   regWaitRCompCnt != regWaitRspCnt
4. ifconfig wlan0 down ; ifconfig wlan0 up ; iwconfig wlan0 essid ...:
   kernel: zd1211.c, line 2413: (enter) kevent
   kernel: zd1211.c, line 668: (enter) zd1211_writel
   kernel: zd1211.c, line 568: (enter) zd1211_USB_PACKAGE_WRITE_REGISTER
   kernel: wlan0: SIOCSIWESSID
   No further output.

Any idea?

Regards
