Ubuntu 22.10 doesn't boot anymore. Upon boot I get the following messages:

[   1.829574] usb 1-3.4: device descriptor read/64, error -32
/dev/sda6: clean, 271463/9601024 files, 15565532/38384128 blocks

[ 319.513256] snd_hda_intel 0000:00:1b.0: Too many BDL entries: buffer=4194300, period=135300

The screen occasionally blinks with more messages but it's too fast to read, and comes back to these messages with an additional snd_hda_intel "Too many BDL entries" error.

The kernel must have been updated from 5.19.0-31 to 5.19.0-35 because I have these two entries in GRUB's advanced options.

The system boots normally with the older kernel version.

I had the same problem previously after a kernel update and I had to reinstall the OS. Let's hope this won't be necessary this time.

Sorry, the question is very vague. please tell me if there is any way I can gather more info.

  • So, from what I understand, your kernel got updated to `5.19.0-35` and it won't boot unless in recovery mode. But there's also an entry for an older `5.19.0-31` kernel — does this one boot normally? – Hi-Angel Mar 08 '23 at 13:21
  • Yes 5.19.0-31 boots without a problem. – Cutter Mar 08 '23 at 13:24
  • I see. So, in this case your further actions depend on what you want. You can remove the newer package *(I think that'd be `sudo apt purge linux-image-5.19.0-35-generic`, check that it doesn't remove any other kernel version)* and avoid updating the kernel for now. You might also want to create a bugreport about this situation on launchpad, to make sure Ubuntu kernel maintainers are aware of this problem, so they'd find a fix. Since the `35` number signifies custom patches, most likely some of the patches maintainers applied to the kernel screwed something up. – Hi-Angel Mar 08 '23 at 13:32

  • @Hi-Angel when I enter the command you gave, apt warns me that it is about to remove the following packages: `linux-generic-hwe-22.04*` `linux-image-5.19.0-35-generic*` `linux-image-generic-hwe-22.04*`, should I do this ? – Cutter Mar 09 '23 at 20:25
  • @karel how can I pin the previous kernel in grub ? Especially since it is hidden in the advanced options. – Cutter Mar 09 '23 at 20:26
  • @Cutter [Set "older" kernel as default grub entry](https://askubuntu.com/q/216398/) – karel Mar 10 '23 at 07:02
  • @Cutter hm, no, you don't want to remove anything except the specific kernel version. Try replacing `purge` with `remove` in my command. Although, I find it odd that it suggests removing the meta-packages, given there is another kernel version that belongs to them… Just for the safe case, before removing, please also make sure there is output for this command `dpkg -l | grep linux-image-5.19.0-31` – Hi-Angel Mar 10 '23 at 07:21
  • I would like grub to remove the new kernel entry and have the "Ubuntu" entry on the main menu point to the previous kernel. How can I do that ? @Hi-Angel is there a boot log that I could provide in my bug report ? – Cutter Mar 12 '23 at 11:48
  • @Cutter assuming that `/` gets mounted correctly, and journal gets flushed before you turn off the computer, you will find the kernel logs from unsuccessful boots at `/var/log/` dir, files with prefix `dmesg` or `kern`. You can make sure you found the correct log by looking up the error messages about `BDL entries` that you know should show up. And regarding you first question about grub entries — simply removing the kernel version that is known to be broken will make default Grub entry point to the older kernel. – Hi-Angel Mar 12 '23 at 12:57

Just hit the same issue here (with 5.19.0.35), purging the new kernel did the trick, before restarting just make sure the old version is still installed.

Thanks for the help.

I still have this problem.

I just had to get back to 5.19.0-32.

35 is not working.

Seems to be something also with nvidia-driver-525.
