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.
