Public bug reported: Today I was hit by this BIOS/UEFI message at boot. UEFI proposed, I delete the unnecessary files. I did, and finally could go back into using the system (with a lot of luck, as I could read later).
Instead of writing with my own words, I refer to the following sources: https://gist.github.com/roadkell/9e98db6656e28fbbf1bf51082040f67f https://unix.stackexchange.com/questions/689158/disabling-writing-dump- files-to-efivars https://bugs.launchpad.net/ubuntu/+source/acpi-call/+bug/1953261 I also refer to my own bug report #2080355, where the same "kernel NULL pointer dereference" still shows on 6.8.0-44-generic, and the presumed fix dated 2022-02-03 (#1953261) still seems to not have made it into 24.04.1. While I can't exclude that the snag encountered today was only the proverbial last straw, even with some intermediate solutions, this must not happen. Meaning, the slow filling up to the brim of the NV storage must by now be halted, and the storage cleaned. It is also amazing, to see that the "kernel NULL pointer dereference" is still ongoing. According to the roadkell document cited further up, sudo dmesg | grep "BUG: kernel NULL pointer dereference" -A 10 shows that this bug still prevails in 24.04.1 with the 6.8.0-44 kernel: [ 9.608433] BUG: kernel NULL pointer dereference, address: 0000000000000028 [ 9.608447] #PF: supervisor write access in kernel mode [ 9.608452] #PF: error_code(0x0002) - not-present page [ 9.608458] PGD 0 P4D 0 [ 9.608468] Oops: 0002 [#1] PREEMPT SMP PTI [ 9.608476] CPU: 0 PID: 150 Comm: kworker/0:2 Not tainted 6.8.0-44-generic #44-Ubuntu [ 9.608484] Hardware name: LENOVO 20CHS10P02/20CHS10P02, BIOS N17ETB6W (2.16 ) 09/02/2021 [ 9.608490] Workqueue: kacpi_notify acpi_os_execute_deferred [ 9.608503] RIP: 0010:klist_add_tail+0x13/0x80 indicating according to this source, that i am still affected by this bug. ** Affects: acpi-call (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080801 Title: Error: The Non-Volatile Variable Storage is About Full To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi-call/+bug/2080801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
