Re: [Bug 1884910] Re: Very slow boot with kernel 5.4.0-37-generic
I have rebooted using the rc6, rc7 and rc8 versions of kernel 5.4. All three booted OK, although I noticed an error message "intramfs unpacking failed, decoding failed" when using rc7. I also tried kernels 5.4.28 and 5.4.41: 5.4.41 booted slowly, with the error messages from the sound system. 5.4.28 booted OK, although it produced the same intramfs error message as rc7.

[Bug 1884910] Re: Very slow boot with kernel 5.4.0-37-generic
Would it be possible for you to do a kernel bisection? First, find the last -rc kernel works and the first -rc kernel doesn’t work from http://kernel.ubuntu.com/~kernel-ppa/mainline/ Then, $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux $ git bisect start $ git bisect good $(the working version you found) $ git bisect bad $(the non-working version found) $ make localmodconfig $ make -j`nproc` deb-pkg Install the newly built kernel, then reboot with it. If it still have the same issue, $ git bisect bad Otherwise, $ git bisect good Repeat to "make -j`nproc` deb-pkg" until you find the offending commit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884910 Title: Very slow boot with kernel 5.4.0-37-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1884910/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 1884910] Re: Very slow boot with kernel 5.4.0-37-generic
I installed the following deb packages for kernel 5.4.51 https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux- headers-5.4.51-050451_5.4.51-050451.202007090834_all.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux- image- unsigned-5.4.51-050451-generic_5.4.51-050451.202007090834_amd64.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux- modules-5.4.51-050451-generic_5.4.51-050451.202007090834_amd64.deb I was unable to install https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux-headers-5.4.51-050451-generic_5.4.51-050451.202007090834_amd64.deb which appeared to match the naming convention of the older kernel files, as its dependencies were not satisfied. I selected kernel 5.4.51 using the grub bootloader, but the boot process was still very slow due to the multiple error messages from the sound system. I have attached the dmesg file obtained during boot-up.
