It's this bug I stumbled into: https://bugzilla.kernel.org/show_bug.cgi?id=214311#c9
Adding "intel_iommu=on iommu=pt" to the kernel parameters in grub made the system find the disks again. I'm unsure if/where/how this could be tackled so that others don't stumble into the issue and have it fixed for good. At least this is a confirmation that this didn't appear with the toolchain in 22.04 but only after the upgrade to 24.04, and it doesn't even seem to be kernel related because the kernel from 22.04 did boot fine with 24.04 if the *old* initrd.img was used, but not the one regenerated in 24.04. ** Bug watch added: Linux Kernel Bug Tracker #214311 https://bugzilla.kernel.org/show_bug.cgi?id=214311 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2076912 Title: broken initrd.img after upgrade to 24.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2076912/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
