Good day everyone,
I have been working with my old laptop to try and avoid having to go
back to Ubuntu 8. Last thing I did was to compile a new kernel (v3.1, talk
about bleeding edge) and the EMC for the new preempt stock kernel options here:
<https://www.gitorious.org/~wangaixi/emc-rt-preempt/wangaixis-emc-rt-preempt/commits/2.4.4-rt-shm>
The kernel runs nicely and fast. EMC, on the other hand, compiles well
but after the splash screen it quits. I have pasted the output on the console
below.
I had thought this version of EMC had been patched to allow it to run
on a non-rtai kernel, did I get that wrong? I see it tries to fetch a module
for a different kernel version, any idea on how can I dig that out? That
version is not mentioned in scripts/emc nor in scripts/emc-environment.
Secondly, has anyone been succesful in compiling and running EMC on
kernel 3.x?
Finally, I have an error in dmesg about the APIC on this box. Tells me
to try to run the kernel with lapic to force enable it, but it won't do it. I
seem to remember vaguely something about removing the support in the kernel for
old APICs but can't find mention of it now googling around. Does this sound
familiar?
Any other ideas appreciated. Here is the console output. Previuos to
this, I have sourced emc-environment:
alfredo@EMC:~/emc-rt-preempt-wangaixis-emc-rt-preempt/scripts$ ./emc
