So I decided to go for Tyan boards, and all the > problems went away. My mobo is ABIT IIRC. I did set ACPI version to 1.1, and tried vanilla 2.4.26 SMP. It did last longer than RH 2188 SMP (the whole weekend, but with near-null load), but today it locked solid right after I logged in and started to use it. Funny thing is that it still worked for a while, but it seems that only while I requested apps that still were in memory. As soon as I demanded data from the HD, the machine hung. Could this be a HD spindown/wake-up problem? I am now trying with HT disabled on BIOS, and with RH 2188 non-SMP kernel. It seems to be working fine, but only time will tell... Any ideas will be much appreciated, I am really disappointed I cannot use SMP with this machine... =/ TIA Andre -- Andre Oliveira da Costa
