Comment (by Miroslav-Stimac):
Hello,
Thank you very much for your response.
Now I tried it with the nightly build r37453 GCC2HYBRID. The system stops
when the second CPU core is enabled.
Meanwhile I enabled on screen log output while booting. The system stops
always at the same line.
publish device: node 0x8226ed70, path power/embedded_controller/0, module
drivers/power/acpi_embedded_controller/device_v1
ahci: ahci_supports_device
When starting from the boot CD of Alpha 2, sometimes it runs a bit longer
and stops a few seconds later, for example when the screen for the
language selection appears.
Please note that I used the safe mode and I disabled all features except
video mode.
Among others, I also disabled ACPI in the Safe Mode Options of the Haiku
boot Loader and I disabled the CPU Power Saving Mode in my BIOS
configuration.
The only option that helped was to disable the second CPU core in the
BIOS, but this is not good because of performance. However, when the
second CPU core is disabled, the system boots without any noticeable
problems and I can use the system.
As I mentioned, the Haiku Alpha 1 version worked with both CPU cores
without any boot problems.
Best wishes,
Miroslav
