kernel module stops working after a while with "No buffer space available" #22

hi,

I have a sun7i arm system running a 3.4 kernel, and a RTL8192CU connected via usb. this works fine for a while, but at some point wireless connections stop working. when new clients try to connect via hostapd, I get this in the logs:

l2_packet_send - send: No buffer space available

stopping and starting hostapd does not solve the problem, but unloading the kernel driver and reloading does! other people seem to have encountered the exact same problem as well: https://www.bountysource.com/teams/rtl8192cu-fixes/issues?tracker_ids=622650

my driver is built from 97351bc01

Please let me know if there is anything I can do to help debug this, it looks like the driver consumes some resource or locks up in some way...
