Comment(by phoudoin):
Sounds more and more related to unmapping physical memmory.
vegardw, siarzhuk, could your try after commenting the RSDP table unmap
in src/add-
ons/kernel/bus_managers/acpi/tables/tbutils.c#AcpiTbParseRootTable, near
line 649:
{{{
#!c
/* It is not possible to map more than one entry in some environments,
* so unmap the RSDP here before mapping other tables
*/
- AcpiOsUnmapMemory (Rsdp, sizeof (ACPI_TABLE_RSDP));
+ /* AcpiOsUnmapMemory (Rsdp, sizeof (ACPI_TABLE_RSDP)); */
}}}
If this unmap do something wrong, without it you should at least see a
different syslog line corresponding to the RSDT/XSDT, less clearly broken
than the one you currently got:
KERN: ACPI: 0xbf7f5d17 00000 (v00 00000000
00000000)
Could be related to MTRR while unmapping, too...
