While running xen-unstable (2005年01月13日 nightly) with dom0 and dom1 with
CONFIG_SMP=y I got 271k of output... sshd was running in dom0 and I remotely
initiated an scp from dom0 to another remote host (not dom1) Ill only post the
first and last few "scheduling while atomic" entries, let me know if someone
wants the whole
trace.
