Yup, the online/offline part works and it helped me to decode the other reason (/me needs a dark brown paperbag) why Pavel noticed that his box turned into a brick. I'll send out a full series of fixups (including your online/offline one) tomorrow morning. I want to give that some more testing. Vs. the resume reevaluation: I don't think it's an urgent problem. It's only my VAIO which does not tell the kernel after resume that the power supply source has changed. All my other boxen do that and we never had a complaint about that from other folks. tglx - 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/
