Further kernel testing on my Lenovo G50-45 with Linux Mint 17.2 Cinnamon, reveals:
PASS - 3.16.0-38-generic #52~14.04.1-Ubuntu PASS - 3.16.0-77-generic #99~14.04.1-Ubuntu FAIL - 3.17.0-031700rc4-generic #201409071935 *diff symptom - lockup, fast cpu fan on first resume. FAIL - 3.17.0-031700rc6-generic #201409211935 FAIL - 3.17.0-031700-generic #201410060605 FAIL - 3.17.4-031704-generic #201411211317 * It also fails on later LM 17.3 (kernel 3.19) and LM 18 kernels 4.4 and 4.7 NOTE that my Lenovo G50 BIOS release A2CN38WW(V2.06) was July 2015 and the other above mentioned Lenovo S435 BIOS release BBCN16WW(V1.07) was June 2015 His PASS on Ubuntu mate 15.10 w/kernel 4.2.0 was due to older BIOS BBCN16WW(V1.03). Hypothesis is still strong that this is due to a BIOS change in mid 2015 to fix VU#976132. Kernel versions released after mid 2015 need to be patched. This is likely true for MANY different computer vendors which use common BIOS suppliers' code. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528735 Title: Suspend fails every second time on some laptops in UEFI mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1528735/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
