    Glad they fixed it so divide by zero doesn't cause more bugs.

      It was not a bug, I was using Zen 1 because of division by zero feature. How am I supposed to do divisions by zero now? T-T

        Can we go a month without a new security disclosure? I know bugs happen and I’m glad that they’re getting fixed, but this is kind of ridiculous.

          Did they just break your user space?

                It's a joke pertaining to a popularly held mathematical calculation. Just had to say it lol. No one else seems to be getting it. I am not trying to be a smart ass I just think it's peculiar and funny considering the title of the post.

                  Hi,

                  I installed Debian 12 x64. New kernel is 6.1.0-11. I want install this new kernel 6.4.10. Is this kernel also for 64 bit system? I installed bio 6.4.9 and had to turn off Secure Boot in the BIOS. After installation, Debian recognizes my USB, but does not open the USB stick. Opens phone, TV Box, ADB, works Scrcpy and everything related to USB except USB stick.

                  I'm new to Linux and maybe I made a mistake somewhere during the installation. Any advice on how to safely install this kernel? Sory for my English.

                  Thank you in advance. Greetings.
