[Bug 1888090] Re: Frequent Kernel panic in 5.4.0-40 but not 5.4.0-29 on Gemini Lake cpu and r8169r
IMHO kernel version 5.4.0-40 should be deleted with the highest prejudice. Never before have I experienced 3 kernel panics in one day and a few after that. This thing should have never left Canonical quality control for an LTS system. And I have been running Ubuntu since the first release.

Things I also tried: * Disabled onboard LAN (r8169) and used a PCIe---(adapter)--->PCI--->Linksys 10/100 NIC (tulip driver). * Disabled all CPU/Chipset features in the BIOS, all APCI/power savings, sleep states, turbo, etc. (Still crashed). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888090 Title: Frequent Kernel panic in 5.4.0-40 but not 5.4.0-29 on Gemini Lake cpu and r8169r To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1888090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
