I'll include those fixes in when I refresh to tip today. If you can, I'd be interested in seeing what process in dom0 is chewing up the cpu if you can get that info. I doubt this is an issue, but can you repro with sedf scheduler as well? And while I don't know much about the credit scheduler, dumping the runqueues 'r' keyhandler might show something to the folks who know the credit scheduler better. Oh, and if you have a log of xen/dom0 booting on your 1 and 2 cell box with out the numa patches on the same changeset, I'd like to see that to compare output. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx (512) 838-9253 T/L: 678-9253 ryanh@xxxxxxxxxx _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
