Is this with next or with mainline? In next we try not to signal that FD is ready unless we have full packet in the buffer...
FWIW I see python indeed not reading the tail of events (btw the format should be 'llhhi' and the size on 64 bit arches is 24, not 16) but when I hacked evtest to use select and non-blockign read it all worked properly.
Thanks.
