Hi Marcelo, please do a
bk pull bk://linux-acpi.bkbits.net/linux-acpi-release-2.4.26
Several key fixes. SCI polarity/trigger fix cardbus bridge interrupt fix maxcpus=N/2 can now be used (like NR_CPUS) to disable HT
thanks, -Len
ps. a plain patch is also available here: ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.4.26/acpi-20040311-2.4.26.diff.gz

When the BIOS enumerates physical processors before logical, maxcpus=N/2 will now effectively disable HT.
This can be verified by boot messages warning that HT is off: eg. "maxcpus=2" on a 2xHT system:
Total of 2 processors activated (11141.12 BogoMIPS). WARNING: No sibling found for CPU 0. WARNING: No sibling found for CPU 1.
