After this happens I can't use the PVTV until I re-plug it. Further testing on this shows that even if I free up lots of memory with sync;echo 3 > /proc/sys/vm/drop_caches giving - DMA: 55*4kB 55*8kB 57*16kB 53*32kB 40*64kB 26*128kB 9*256kB 4*512kB 2*1024kB 0*2048kB 0*4096kB = 15556kB Normal: 2996*4kB 2169*8kB 1616*16kB 1021*32kB 596*64kB 221*128kB 45*256kB 2*512kB 0*1024kB 0*2048kB 0*4096kB = 166840kB It will still fail if it has already failed and not been replugged. It's not failing to allocate - it's just not trying to allocate AFAICT , which I guess counts as a bug?
