I have installed it on 28 production servers with that patch contributed by William Lee Irwin III including Dell Servers and 2 Compaq servers among other types of hardware with 3ware, MPT SCSI, straight IDE, MylexRaid in the mix. I have reported no problems with them and they all correctly reported the HyperThreading CPUs. Previous versions since 2.4.21 have problems reporting the Hyperthreaded Dual Xeons and report it as 2 CPUs instead of 4. So..I recommend this patch being pushed to 2.4.x tree for inclusion. Here is a snippet of one of the servers that is made possible with the patch: Linux version 2.4.23-ow1 (root@tiamat.nosdns.com) (gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)) #2 SMP Sat Dec 6 03:34:00 CST 2003 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 00000000000a0000 (usable) BIOS-e820: 0000000000100000 - 000000007fff0000 (usable) BIOS-e820: 000000007fff0000 - 000000007fffec00 (ACPI data) BIOS-e820: 000000007fffec00 - 000000007ffff000 (reserved) BIOS-e820: 00000000fec00000 - 00000000fec10000 (reserved) BIOS-e820: 00000000fee00000 - 00000000fee10000 (reserved) BIOS-e820: 00000000fff80000 - 0000000100000000 (reserved) 1151MB HIGHMEM available. 896MB LOWMEM available.
