Yu, Luming <luming.yu@intel.com> asked me to try boot option: ec_intr=0. Here are the results: PM: Finishing wakeup. acpi: resuming ACPI Exception (evregion-0412): AE_TIME, Returned by Handler for [EmbeddedControl] [20060310] ACPI Exception (dswexec-0459): AE_TIME, While resolving operands for [Store] [20060310] ACPI Error (psparse-0522): Method parse/execution failed [\_TZ_.THRM._TMP] (Node c189ec44), AE_TIME agpgart-intel 0000:00:00.0: resuming So, booting with this option causes the "ACPI: read EC, IB not empty" and "ACPI: read EC, OB not full" to stop showing up. Hmm, I see AE_TIME, Returned by Handler for [EmbeddedControl] in both cases: ec_intr=0, ec_intr=1. It means ec hardware doesn't respond to the ec read/write/query command. I recall this is a known and not resovled issue. What is the laptop brand and model? What is the kernel version? Maybe it is time to fix it. I don't want to lose it again. My laptop is an HP Pavillion dv1240us. I have reproduced the problem with 2.6.17-rc6-mm1. My distro is Ubuntu 6.06 LTS. 1st step: 1. remove thermal & processor module in kernel. Re-test. Please reopen this bug: - it is still present in kernel 2.6.18-rc6 and - you can provide the requested information. |
