Hi Michael:
Sorry to brother. But I've been suffered this issue quite a long time.
My test environment is 2.6.32.36 + xen 4.0.1 + bnx2, 2.3.
Also cpu idle is disabled in grub.
Grub info:
title Red Hat Enterprise Linux Server (2.6.32.36xen)
kernel /xen-4.0.1.gz iommu=off x2apic=off console=com1,vga com1=115200,8n1 noreboot cpuidle=0 cpufreq=none no-xsave max_cstate=1
module /vmlinuz-2.6.32.36xen ro root=LABEL=/ hda=noprobe console=hvc0 console=ttyS0,115200n8
module /initrd-2.6.32.36xen.img
Someone has pointed out that this might be interrupt lost, but I don't understand the log info, if the log
info is documented somewhere, could you let me know?
Many thanks.
