I was surprised the whole thing went away with the firmware upgrade (I saw some message in /var/log/messages telling me the firmware was old) - it did seem like something more serious. I hit another problem. On a quad code intel machine here at home there is a problem during shutdown. The final shutdown dies with a traceback (something like "rc0 was killed by SIGSEGV" or similar words at the very end). Then I have to push the power button for x+ seconds to force a power off. Should I post a picture of the screen as it is at that point, or just send that to you and Thomas? -- Fernando -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
