I have a similar behaviour (hangs) recently, once with a corrupted filesystem, had to force shutdown laptop several times a day. Today when I was in console and not GUI (because the hang happened already during logging in to Xfce and I was lucky to be able to switch via Ctrl-Alt-F1 to console, I finally saw the Kernel Oops.
Using Mint 19.3 on HP ProBook 6470b/179B BIOS 68ICF Ver F.73 08/07/2018 CPU Intel(R) Core(TM) i5-3340M CPU @ 2.70GHz Message on the console when system crashed: BUG: unable to handle kernel paging request at 000000d4b2d9323e IP: __handle_mm_fault+0x5b/0xff0 PGD 0 P4D 0 Oops: 0000 [#2] SMP PTI ... entire trace I have in a photo of the screen if necessary. Laptop was rock stable until recently and it appears the previous 4.15.0-147-generic #151-Ubuntu SMP kernel is OK, currently running at this kernel and decided to remove for now the probably problematic kernel and block auto-updates to it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938013 Title: 4.15.0-151 is freezing intel 5th gen ThinkPad (T450) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938013/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
