We are running latest debian stable release. ii libxenstore3.0 4.0.1-2 =20 ii linux-image-2.6.32-5-xen-amd64 2.6.32-35squeeze2 ii linux-image-xen-amd64 2.6.32+29 =20 ii xen-hypervisor-4.0-amd64 4.0.1-2 =20 ii xen-linux-system-2.6-xen-amd64 2.6.32+29 =20 ii xen-linux-system-2.6.32-5-xen-amd64 2.6.32-35squeeze2 ii xen-qemu-dm-4.0 4.0.1-2 =20 ii xen-tools 4.2-1 =20 ii xen-utils-4.0 4.0.1-2 =20 ii xen-utils-common 4.0.0-1 =20 ii xenstore-utils 4.0.1-2 =20 We also have the clock jumping 50 minutes into future.=20 We are running IBM Blades HS21 XM (Type 7995) with Intel(R) Xeon(R) CPU E5345 @ 2.33GHz. We are also running the same configuration on another machine with Intel(R) Xeon(R) CPU X7550 @ 2.00GHz where we dont experience this problems. Also w= e didnt had those bugs running xen 3.1.0 with 2.6.18-5-xen-amd64 kernel. We currently running one blade with disabled HPET, clocksoure=3Dpit and cpuidle=3D0 and another with HPET on and nothing else configured. The main problem debugging this, is to wait for the next error to appear. Until now both machines run fine without time jumping, but we did see that time jump on the machine which is running with hpet enabled and no other settings.=20 We could help debugging here.
