Well, you need to run the following script when the machine boots. I.e., you'd probably have to add it to /etc/init.d/ and make it run at some runlevel, sometime early-ish, before a user can login. Here's the script, let me know how it goes: -- #!/bin/bash # assuming a single CPU system nb_cfg=0xc001001f ht_tr_ctl=0x68 val="0x"$(rdmsr $nb_cfg) val=$(( $val | (1 << 32) )) val=$(printf "0x%08x" $val) wrmsr $nb_cfg $val val="0x"$(setpci -s 18.0 $ht_tr_ctl.l) val=$(( $val | (1 << 21) )) val=$(printf "0x%08x" $val) setpci -s 18.0 $ht_tr_ctl.l=$val echo "Erratum 169 workaround applied." --- HTH. -- Regards/Gruss, Boris.
