Gentoo on a Dell Poweredge 2650
Just recently I have been trying to get SMP + Hyper-Threading enabled on our 2650, this has caused me no end of grief. I have finally managed to get a working (and stable!) kernel compiled. The version I am using is 2.4.22 from the vanila-sources, which is the same as 2.4.22 downloaded from kernel.org (or a mirror)
The .config file for my working kernel is here, although the important bits are:
- CONFIG_SMP=y
- CONFIG_ACPI=y
- CONFIG_ACPI_HT_ONLY=y
- CONFIG_RTC=y
When this is booted with the extra command line arguments acpi=ht HT works. Now i wonder if HT actually makes that much difference!
