[Bug 1845454] Re: Kernel panic with 19.10 beta image
** Description changed:
+ SRU Justification
+
+ Impact: Some systems are getting kernel panics during boot while parsing
+ tpm event logs from the firmware. This happens only when the tpm and
+ secure boot are both enabled in the firmware.
+
+ Fix: 3 patches which are currently applied to the upstream EFI
+ maintainer tree.
+
+ Test Case: On an affected system, booting a 5.3-based kernel will panic
+ during boot when the tpm and secure boot are enabled. A patched kernel
+ will boot successfully. The patches have been verified to fix the issue
+ on a gen 6 Lenovo X1 Carbon.
+
+ Regression Potential: If the patches have bugs they could cause
+ regressions on systems not currently experiencing issues. The patches
+ are pretty straightforward though, so I believe the risk is minimal and
+ (given the severity of the issue on affected hardware) acceptable.
+

Image: http://cdimage.ubuntu.com/daily-live/20190926/eoan-desktop-amd64.iso
Device: Dell XPS 13 7390 (201908-27305)
When trying to start the live session ("try Ubuntu") or trying to
install the ISO ("install Ubuntu"), the boot process stops within 1
second with a kernel panic (see attached screenshot).
The system could boot with a previous version of Eoan image: 2019-09-09
09:11 (kernel 5.3.0-10)
Workaround: disable TPM2 in the BIOS.
/!\ Please note: the information below (and the attached file
ProcCpuinfoMinimal.txt) come from a 18.04 live session, since I cannot boot
anything with 19.10 beta image.

[Bug 1845454] Re: Kernel panic with 19.10 beta image
This is the same bug as bug 1844101 I think? If it is, it doesn't reproduce with secure boot off and we'll need a signed kernel to test. I'm happy to enrol whatever key in my firmware to test a self-signed kernel... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845454 Title: Kernel panic with 19.10 beta image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845454/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1845454] Re: Kernel panic with 19.10 beta image
I agree this looks the same as the bug reported against fedora. I've started a test build with these commits. I know this was reported with the ISO image, but hopefully we can work out a way to test. I suspect disabling the tpm in the firmware settings will get the machine to boot/install, and then it could be re-enabled to confirm that the panic still happens with the kernel from -release and to check whether it is gone in the test build. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845454 Title: Kernel panic with 19.10 beta image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845454/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
