Public bug reported: SRU Justification:
[Impact] Some systems have enabled ISH without any sensors. In this case sending HOSTIF_DM_ENUM_DEVICES results in 0 sensors but triggers ISH hardware reset on subsequent enumeration after S3/S4 resume. [Fix] Backport the fix from Intel https://lore.kernel.org/linux-input/[email protected]/T/#m13f2b9138d5ff1883e1bca804f77c00b47ac0d0f [Test Case] 1. Boot up the problematic machine Dell Pro MFF TC. 2. Click sleep and wait 30 mins 3. Resume and do basic function check(audio/network/externel ports) and idle to 30 mins 4. Repeat run 3 cycles w/o any unexpected reboot [Where problems could occur] Reset enum_devices_done to false before sending the enumeration command, which should be consistent with other similar function. Should be low risk of regression ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux-oem-6.14 (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-6.17 (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-6.14 (Ubuntu Noble) Importance: Undecided Status: New ** Affects: linux-oem-6.17 (Ubuntu Noble) Importance: Undecided Status: New ** Tags: jira-wtn-328 oem-priority ** Also affects: linux-oem-6.17 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-oem-6.14 (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: linux-oem-6.17 (Ubuntu Noble) Importance: Undecided Status: New ** Tags added: jira-wtn-328 oem-priority -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2135086 Title: Fix random auto reboot after resume from suspend on Intel platforms To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2135086/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
