probably to early to tell if this patch is working or not(since this bug
is shows up randomly), but I have applied this to the current Mainline
and am so far not seeing the DMA failed to stop
as for any issues: waking up from suspend I get no
connection(rmmod/modprobe recovers this) then after a few suspends the
connection is real crappy(on and offline).
dmesg with debug gives me this:
