RE: [Xen-devel] Test report for Xen-3.2.3-rc1 (#17021)



Hi Keir,

More clear description of bug #1395 is that "On PAE host, sometimes SMP Linux 
HVM would stop at booting if timer_mode=0, but it still can respond to keyboard 
input.". 

This bug is not a regression. Xen-3.2.2 also has same issue. It should be a bug 
of timer_mode 0; but it does not always cause SMP Linux HVM booting failure, 
i.e. sometimes SMP Linux can boot up successfully with timer_mode 0; that's 
also why we didn't catch this bug out in our 3.2.2 testing.

We double checked timer_mode 1, 2 and 3, all can work fine without this issue.
