I had a bunch of issues on 2.6.31, including sky2 DMAR errors... so probably not a 2.6.32 regression. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Another things IMHO worth to try: a sky2 module parameter "disable_msi=1", and CONFIG_DMAR off.

(note that so-far, without MMAP I'm not seeing any errors - throughput is running about half what I was seeing with MMAP enabled (before crashing that is). CPU is also way busier (also to be expected). One other observation - I had been seeing lots of DNS errors - IPV6 related format errors I really didn't think much of it as they were mostly .ru and seemed spam-related, but now I don't see any. Haven't updated bind; doubt the world has changed - so perhaps this is related to the network issue. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
