Subject: VMI broken on tip/master...
Date: Fri, 13 Mar 2009 10:56:08 -0700	[thread overview]
Message-ID: <1236966968.14680.15.camel@alok-dev1> (raw)

Hi Peter, 

I was seeing a early fault when running tip/master with VMI enabled on
VMware platform. 
This early fault was in the vmi_patch code where we are applying
paravirt_alternatives. After some trials i noticed that this is
reproducible only with CONFIG_TRACING. With that disabled my VM boots
again. 

I started a git bisect after that, and git pointed to this as the bad
commit

commit 6cc3c6e12bb039047974ad2e7e2d46d15a1b762f
    trace_clock: fix preemption bug

I then reverted that commit from tip/master and the system did boot. 
But I fail to understand how this simple patch would be causing things
to fail in VMI. Any ideas ?

Thanks,
Alok
