Thanks Martin for your response.
I have followed your suggestion, and this is pretty much what I can see
from the output right before the booting process freezes:
...
0x819dbff4:generic/src/proc/thread.o:cushion()+0x00000059
generic/src/lib/func.o:halt()+0x0000005a->generic/src/console/kconsole.o:kconsole_check_poll()
generic/src/lib/func.o:halt()+0x0000005a<-generic/src/console/kconsole.o:kconsole_check_poll()
cpu0:halted
cpu1:halted
cpu2:halted
cpu3:halted
cpu4:halted
cpu5:halted
cpu6:halted
cpu7:halted
I have tried with gPXE as well, with same result.
Nevertheless, I have been able to run HelenOS, from CD, in a 48-cores
AMD Opteron Magny-Cours server, which unblocks me for now. However, when
I execute 'cpus' in the kconsole, it tells me only the first eight cores
are active. Is this a HelenOS limitation? Is there some flag I need to
turn on in order to have all the 48 cores active?
Thanks,
Amadeo

Hello Amadeo,
I am trying to boot HelenOS in a 64-bit machine from the network, but I
haven't been able to do so successfully. I have tried with Pulsar PXE
Loader.
The first think to try in these situations is to compile HelenOS with
the following options:
Detailed kernel logging -> ON
Kernel function tracing -> ON
EGA support -> ON
Framebuffer support -> OFF
This will use just the EGA/VGA text mode and print a verbose (very
verbose) output of the actions the kernel is performing during the boot
process. You can tell quite easily by this if the code got stuck somewhere.
Also, if there is some early kernel panic, you will see the panic message.
If this does not help, we would probably need to replicate your setup
(i.e. try to boot from the network using Pulsar PXE ourselves) and see
what's happening.
Best regards
Martin Decky
