Public bug reported: [Impact] ACPI error can be found in kernel message: [ 3.717920] ACPI Error: No handler for Region [SYSI] (00000000ab9e62c5) [IPMI] (20230628/evregion-130)
[Fix] On Dell systems that have IPI0001 device, ensure IPMI region is ready before acpi_power_meter invokes any ACPI method. [Test] With the patch applied, no such error can be found in kernel message. acpi_power_meter sysfs also works correctly. [Where problems could occur] If asynchronous probe is disabled, the device drivers that probe after acpi_power_meter needs to wait until the completion is done, hence the boot time might be slower. ** Affects: linux (Ubuntu) Importance: Medium Status: Confirmed ** Affects: linux-oem-6.5 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Jammy) Importance: Undecided Status: Won't Fix ** Affects: linux-oem-6.5 (Ubuntu Jammy) Importance: Medium Status: Confirmed ** Affects: linux (Ubuntu Mantic) Importance: Medium Status: Confirmed ** Affects: linux-oem-6.5 (Ubuntu Mantic) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Noble) Importance: Medium Status: Confirmed ** Affects: linux-oem-6.5 (Ubuntu Noble) Importance: Undecided Status: Invalid ** Also affects: linux (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Mantic) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Noble) Status: New => Confirmed ** Changed in: linux (Ubuntu Mantic) Status: New => Confirmed ** Changed in: linux (Ubuntu Mantic) Importance: Undecided => Medium ** Changed in: linux (Ubuntu Noble) Importance: Undecided => Medium ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Jammy) Status: New => Won't Fix ** Also affects: linux-oem-6.5 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-oem-6.5 (Ubuntu Jammy) Status: New => Confirmed ** Changed in: linux-oem-6.5 (Ubuntu Mantic) Status: New => Invalid ** Changed in: linux-oem-6.5 (Ubuntu Noble) Status: New => Invalid ** Changed in: linux-oem-6.5 (Ubuntu Jammy) Importance: Undecided => Medium -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2059263 Title: Fix acpi_power_meter accessing IPMI region before it's ready Status in linux package in Ubuntu: Confirmed Status in linux-oem-6.5 package in Ubuntu: Invalid Status in linux source package in Jammy: Won't Fix Status in linux-oem-6.5 source package in Jammy: Confirmed Status in linux source package in Mantic: Confirmed Status in linux-oem-6.5 source package in Mantic: Invalid Status in linux source package in Noble: Confirmed Status in linux-oem-6.5 source package in Noble: Invalid Bug description: [Impact] ACPI error can be found in kernel message: [ 3.717920] ACPI Error: No handler for Region [SYSI] (00000000ab9e62c5) [IPMI] (20230628/evregion-130) [Fix] On Dell systems that have IPI0001 device, ensure IPMI region is ready before acpi_power_meter invokes any ACPI method.
