For information, ubuntu-24.04 has updated Linux kernel from 6.5.0-28 to 6.8.0-31
The problem reported is with newer 6.8.0-31, and also failure to reach a working system is only with new kernel. The previous Linux kernel is still available in the Grub menu, and choosing "6.5.0-28-generic" to boot does bring a working system. I still get with the older and working kernel: etienne@etienne-MS-7D77:~$ sudo dmesg | grep -A1 array- [ 3.078005] UBSAN: array-index-out-of-bounds in /build/linux-hwe-6.5-5nKPnc/linux-hwe-6.5-6.5.0/drivers/gpu/drm/radeon/radeon_atombios.c:2717:34 [ 3.078010] index 18 is out of range for type 'UCHAR [1]' -- [ 3.078476] UBSAN: array-index-out-of-bounds in /build/linux-hwe-6.5-5nKPnc/linux-hwe-6.5-6.5.0/drivers/gpu/drm/radeon/radeon_atombios.c:2715:55 [ 3.078481] index 1 is out of range for type 'UCHAR [1]' -- [ 3.078932] UBSAN: array-index-out-of-bounds in /build/linux-hwe-6.5-5nKPnc/linux-hwe-6.5-6.5.0/drivers/gpu/drm/radeon/ci_dpm.c:5588:32 [ 3.078938] index 9 is out of range for type 'UCHAR [1]' -- [ 4.170748] UBSAN: array-index-out-of-bounds in /build/linux-hwe-6.5-5nKPnc/linux-hwe-6.5-6.5.0/drivers/gpu/drm/amd/amdgpu/../display/dc/bios/bios_parser2.c:683:23 [ 4.170803] index 8 is out of range for type 'atom_gpio_pin_assignment [8]' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065406 Title: kernel UBSAN array-index-out-of-bounds in AMD video card Edit To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/2065406/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
