Tashkinov (aros@gmx.com) --- I'm not an expert bug your backtrace looks weird. Please run memtest86 or memtest86+ for an hour or two. https://www.memtest86.com/download.htm https://github.com/memtest86plus/memtest86plus/releases I'm also removing the bisected ID because it doesn't look like it has anyth= ing to do with this issue. You don't just copy random stuff from other bug reports which look similar = to yours. You actually bisect and provide the full bisect history. Ubuntu 22.10 comes with kernel Kernel 5.19. Ubuntu 23.10 comes with kernel Kernel 6.5. That's a very large regression window. And then you can only bisect on vani= lla kernels, not Ubuntu ones. First compile and make sure 5.19 absolutely works= for you. Then try consecutive kernels one by one. If you hit the issue, then you will have just two kernel releases to work with, instead of trying to find = the regressions between two very distant kernels. https://docs.kernel.org/admin-guide/bug-bisect.html Best of luck. --=20 You may reply to this email to add a comment.
