[Bug 1900728] Re: Ubuntu boot failure after upgrade to kernel 5.4.0-52
Recovery mode does not boot for 5.0.4-52 I loaded mainline kernel 5.4.0, and that does not boot either. I got this message from initramfs: "Initramfms unpacking failed: Decoding failed Couldn't get size: 0x8. irq 31: nobody cared (try booting with the "irqpoll" option) handlers: [<9ra32e4e>] tis_int_handler Disabling IRQ #31" FWIW, when I boot into 5.0.04-52, I don't get any messages in initramfs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1900728 Title: Ubuntu boot failure after upgrade to kernel 5.4.0-52 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1900728/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Does 5.4.0-52 boot into recovery mode?
