I have patched kernel 2.4.4 with rtlinux 3.1. to get hard real time capability.
The patch is the GPL version of RT Linux Pro by FSM labs. I know of the
patch reliability from people I know.
Running a real time module is fine but when shutting down the machine,
the hdd NEVER unmounts properly.
This problem only happens after running a real time module, i.e.
booting with the real time kernel and NOT using the real time capability
does NOT cause the hdd to unmount improperly.
Any ideas anyone ?
