@Michael Hudson-Doyle, After some more testing I have to add some (maybe confusing, maybe helpful) information:
A - The bug appears in 1. a Toshiba laptop with an Intel i5 generaton 3 CPU (in BIOS mode and UEFI mode) http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/ This Toshiba laptop has been my main testing computer for several years. 2. a Dell laptop with an Intel i5 generation 4 CPU (in BIOS mode and UEFI mode) https://www.cnet.com/products/dell-latitude-e7240-12-5-core-i5-4310u-8 -gb-ram-128-gb-ssd-english/specs/ 3. A Lenovo laptop with an Intel i3 generation 2 CPU (tested only in UEFI mode) https://shop.lenovo.com/ISS_Static/ww/wci/products/us/laptop/thinkpad/x-series /x131e-intel/X131e-Datasheet-Intel.pdf B - The bug does *not* appear in 1. an HP Probook 6450b laptop with an Intel i5 M520, tested only in BIOS mode 2. a Lenovo V130-14IKB laptop with an Intel i5 generation 7 CPU (rather new), tested only in UEFI mode 3. a Dell laptop with an Intel i7 generation 4 CPU (in BIOS mode and UEFI mode) https://www.cnet.com/products/dell-precision-mobile- workstation-m4800-15-6-core-i7-4810mq-8-gb-ram-256-gb-ssd-english/specs/ --- I think that there is some kind of race condition as you suspected already in comment #4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863672 Title: The 'new' persistent live method starting in 19.10 no longer works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1863672/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
