When running a scp transfer using a USB/Ethernet adapter the following crash happens: $ scp test.tar.gz fabio@192.168.1.100:/home/fabio fabio@192.168.1.100's password: test.tar.gz 0% 0 0.0KB/s --:-- ETA ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x2cc/0x2f0() NETDEV WATCHDOG: eth0 (asix): transmit queue 0 timed out Modules linked in: Backtrace: [<80011c94>] (dump_backtrace+0x0/0x10c) from [<804d3a5c>] (dump_stack+0x18/0x1c) r6:000000ff r5:80412388 r4:80685dc0 r3:80696cc0 [<804d3a44>] (dump_stack+0x0/0x1c) from [<80021868>] (warn_slowpath_common+0x54/0x6c) [<80021814>] (warn_slowpath_common+0x0/0x6c) from [<80021924>] (warn_slowpath_fmt+0x38/0x40) ... Setting SDIS (Stream Disable Mode- bit 4 of USBMODE register) fixes the problem. However, in current code CI13XXX_DISABLE_STREAMING flag is only set in udc mode, so allow disabling streaming also in host mode. Tested on a mx6qsabrelite board.
