| pitti | hello everyone! | 09:28 |
|---|---|---|
| pitti | in 22.04 and kinetic it takes almost 20s to get from grub's "boot now" (Ctrl+X) to the first line of kernel output, even with enabling "debug" | 09:29 |
| pitti | with Fedora that takes a mere 3s; any idea how to debug that? it feels like grub takes an awful amount of time to unpack the kernel or so? | 09:30 |
| pitti | indeed when I drop the "initrd" line, it boots almost immediately (of course with a kernel panic, as it can't find the root fs); but that points to awfully slow initrd unpacking | 09:37 |
| pitti | eww -- initrd.img-5.15.0-41-generic is 102 MB! no wonder it takes so long | 09:52 |
| tarzeau | pitti: mine are only 35 MB, i use: /etc/initramfs-tools/conf.d/compress:COMPRESS=xz | 10:45 |
| tarzeau | oh wait 22.04 110 MB, 35 MB was 20.04 | 10:45 |
| pitti | I left my observation in https://bugs.launchpad.net/cloud-images/+bug/1592684/comments/8 | 10:46 |
| ubottu | Launchpad bug 1592684 in cloud-init (Ubuntu) "Add MODULES=dep initramfs configuration" [Wishlist, Triaged] | 10:46 |
| rbasak | Is anyone working on the Haskell transition? I've been digging into it, but some of the issues seem quite deep. | 13:59 |
| seb128 | pitti, hey. could that also have to do with the compression in use? what kind of hardware are you seing those numbers on? | 14:03 |
| pitti | seb128: yes, could be -- even decompressing 100 MB shouldn't take 18 MB; I see it in qemu-system-x86_64 -enable-kvm with the defaults (1 CPU, $whatever model) and 2 GiB RAM | 14:09 |
| pitti | but either way, I got it down to 18 MB and < 2s now, good enough | 14:10 |
| seb128 | pitti, nice improvement :) | 14:16 |
| pitti | "even decompressing 100 MB shouldn't take 18 MB" -- d'oh, of course I meant "18 seconds" 🙈 | 14:20 |
| seb128 | :) | 14:24 |
| seb128 | still weird indeed, on a modern hardware in a qemu even with 1 CPU I would expect decompression to not be that slow :/ | 14:25 |
| Odd_Bloke | Hey folks, not sure if these MPs are monitored so: I have a small fix to avoid reporting that NBD devices will get fsck'd: https://code.launchpad.net/~oddbloke/update-notifier/+git/update-notifier/+merge/427497 | 14:27 |
| dbungert | Retest click please? retry-autopkgtest-regressions|grep package=livecd-rootfs | 14:53 |
| Eickmeyer[m] | vorlon: How would you like to proceed on digikam? I can upload my fix now, or you can upload a with a patch to port it to ffmpeg5, or I can do mine now and you can do yours later or not at all? | 15:36 |
| bdmurray | dbungert: I'll retry them and use it as an opportunity to try out --blocked-by-tests | 15:43 |
