It happens, sorry I broke it... sometimes you can log in using another kernel on your system and resolve. I just can't remember how but I have been caught a few times...

Say 200 uS after 10 minutes or so:

chrt 99 ping -i .0005 -c 600000 -q 10.10.10.10

The answer is always "it depends". In some kernel traces we did, at 1 kHz, the servo thread was done in around 200 usec and it slept for the remaining 800 usec. On a 2 Khz servo thread, it must be done in 500 usec so in theory, the hardware we had would meet the requirements.
