Hi all. I am wondering whether anybody else has experienced lock-ups when trying to mount a CD-ROM device using kernel 2.4.21 with low latency and preempt? I have tried with SCSI emulation, as well as normal IDE. I am currently re-compiling without low latency and pre-empt, but wondering whether this is a reported kernel problem, or a problem that these patches may have introduced? Any ideas or suggestions are welcome. Regards Luke
