What steps will reproduce the problem?
Testrun of PsychRTBox on Linux 3.2.0-rc7 seems to indicate bad syncClocks
timing for host clock <-> RtBox clock calibration. Reproduced on Ubuntu 10.10 +
MBP and Ubuntu 11.10 + Dell WS. No such problem with Linux 3.0.0 stable kernel.
Investigate: A bug in Linux ftdi_serio driver? Or some other change in
sysconfig? Suspect: No proper blocking of write()'s / tcdrain() or
missing/wrong flushing of usb write buffers? Or because or old sync strategy is
not valid anymore and we should use the same method as on os/x and windows,
discarding the linux specific, higher accuracy method?
Target: Investigate before 12.04-LTS release, which uses Linux 3.2.0 kernel.
