Yes. The latest working version is c047211. I got 2 different kind of errors with a guest setup with 2 VCPUs: 1) Hackbench gets stuck and use 100% of the CPU. 2) Hackbench heap gets corrupted For the former, I was thinking about a possible missing SGI. >> FYI, I'm not able to reproduce on our local midway node. > > Without a reproducing environment is going to be very hard to fix it. > It might be worth living it running in a loop for a few hours... Sorry I meant I'm able. I spent my afternoon to set up the same environment as the CI loop. It looks like the bug is likely the same on the Arndale, even if WFE is not trap. I will try to bisect on this board. Regards, -- Julien Grall _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
