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

Is it possible your old kernel has DMA off for the CD-ROM and the new kernel
has DMA on? It is pretty common for IDE CD devices to claim they are DMA
capable, but not work properly in Linux when DMA is enabled. You probably
would want to use the "hdparm" utility to check this.
