First of all 2.6.18 is not only old, it is a security risk. Seriously, why do you (OP) even bother to sent an email to the list without first upgrading to a more recent one and checking if the problem persists? It's exactly like Kashani and Keith suspected: It's a VPS and I have no influence on the kernel. Well, at least it's no longer version 2.6.9 like it was with the last VPS. signature.asc Description: OpenPGP digital signature

[gentoo-user] Interpreting /proc/cpuinfo
Hi list!

Could the missing flags be related to a too old kernel (2.6.18)? Thanks in advance! Florian Philipp signature.asc Description: OpenPGP digital signature

Cause if you've been following Florian's post you'd see that he's running a VPS which is probably a heavily patched 2.6.18. At least my VPS is like that. Come on, don't you read everyone's post? Yeah BIOS can effect it, the kernel not so much. Not sure about an openvz style VPS. kashani
