[Xen-users] "BUG: soft lockup detected on CPU#n", results in very slow domU''s
Hello, Recently, I''ve installed Xen 3.2 (fresh from Mercurial) on a Compaq Proliant DL580 machine with 4x 700MHz Pentium III Xeon CPU''s and 4GB of RAM. However, whenever I boot Xen, I see the following messages in my dom0''s dmesg: BUG: soft lockup detected on CPU#3!

Does anyone have a clue what is going on? The machine works fine without a Xen kernel... Regards, -- Rink P.W. Springer - http://rink.nu "Anyway boys, this is America.

If not CPU scaling, then any other CPU idle throttling function. -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
