I believe there is no support for xenoprofile in 3.0.2
It works in 3.0.0

It's back!

I'm trying to run xenoprof on an Intel VT platform (955 processor) under
latest xenbits unstable (well, when I downloaded it last night, it was
changeset 10031, and I'm getting the following when I run opcontrol:

You cannot specify any performance counter events
because OProfile is in timer mode.

The opreport command line in question is:

opcontrol \ 
--vmlinux=/home/raybry/xenbits-unstable.hg/linux- \

--xen=/home/raybry/xenbits-unstable.hg/xen/xen-syms --active-domains=0 

The xen command line in /boot/grub/menu.lst includes the lapic option:

title XENbits unstable xen
    root (hd0,1)
    kernel /boot/xen.gz lapic dom0_mem=512M tbuf_size=100
console=com1 cdb=com1 sync_console
    module /boot/vmlinuz-2.6.16-xen root=/dev/sda2 selinux=0 showopts 
psmouse.proto=bare lapic
    module /boot/initrd-2.6.16-xen

Attached is the xen.dmesg, the linux.dmesg, .config file for the 
linux- kernel, and some system info.

Any suggestions would be appreciated.
