Haiku booting breaks with "Machine-Check Exception"

[e_barsukowski]

I try to run Haiku hrev30998 on real hardware. My machine has Intel DG33FB motherboard based on G33 chipset, Core2 Duo E6750 CPU and 2GB of RAM.

Without additional options the boot process hangs at the 5th icon half typing messages like "allocate_commpa" or "allocate_commpage_entr" at the serial debug. Keyboard (PS/2) stops working, so the only way out is hardware reset.

Disabling SMP (either in BIOS or via safe mode options) leads to the following message:

<...>
  trying: file_systems/nfs/v1
  returned: -1
  trying: file_systems/write_overlay/v1
  returned: -1
allocate_commpage_entry(4, 34) -> 0xffff0118
PANIC: Fatal exception "Machine-Check Exception" occurred! Error code: 0x0

kdebug>

The KDL prompt appears only on serial debug but not on the screen. The keyboard seems to work. After I type "sc" and hit <Enter> Haiku prints some lines at the debug output (there is still nothing on the screen) and freezes. Again nothing but reset helps.

Here's the output of "sc":

allocate_commpage_entry(4, 34) -> 0xffff0118

Can you check if this is fixed at hrev31027? From where it happens this could very well be an MTRR issue.

[e_barsukowski]

I've updated to hrev31038 and it works! Haiku boots without problems.

Thank you!

Thanks for the upsate! Fixed as part of recent MTRR changes.
