RE: [Xen-ia64-devel] Xen/IA64 Healthiness Report -Cset#15666

["Yang, Liuqing" <liuqing.yang@xxxxxxxxx>]

Hi, Alex,
About the SMPWin_SMPVTI_SMPxenU_Co case fail, the open guest firmware do not 
have this bug, but since the open guest firmware can not support our nightly 
test automatic test(it don’t have nvram file for windows vti automatic 
booting), so we do not use it now. And about the older guest firmware,in the 
SMPWin_SMPVTI_SMPxenU_Co case when booting linux vti it usually can not 
uncompressing  linux kernel immediately, so it will repeat uncompressing the 
linux kernel until it succeed.  

About XenU case fail, I have retested the changeset 15666, and I found that if 
I just tried only one xenU case it usually passed, and if I test more cases 
including xenU case sequentially, the bug usually occurred. But with changeset 
15659 this bug occurs rarely. 

Best Regards
Liuqing

Hi Liuqing,

   The previous testing on 15665 indicated this issue, but manual
testing passed.  What's changed that makes it so much more repeatable
now?  Changeset 15666 surely can't be contributing to this.  I've
noticed some semi-random failures with xm for a while (mainly it gets
into a state where most xm commands hang), but I haven't been able to
characterize what causes it.  Going back to cset 15659 would implicate
the pkr patches, but I've created plenty of PV domains with those
patches in place.  Any ideas?

   With the older GFW, where was the retry of the uncompress occurring?
I don't think elilo has support for this.  Was it the GFW retrying
elilo?  What happens with the open source GFW?  Thanks,

        Alex
