@lily:lily.flowers | Something about loading 9p after /sysroot tmpfs is mounted breaks it | 17:25:02 |
@lily:lily.flowers | (and yes it did also need the sleep) | 17:25:10 |
@lily:lily.flowers | nikstur | 17:25:17 |
@lily:lily.flowers | Scripted stage-1 only works because it handles that specially and serially rather than generally and parallel like systemd-initrd | 17:25:40 |
@nikstur:matrix.org | I figured it would be something like this... :(( | 17:37:11 |
@lily:lily.flowers | Looks like 6.3 still has the same problem and I'm testing 5.15 now. I didn't find any immediately obvious related bug reports on lkml or bugzilla, but I also didn't look too hard and not sure which exact part of that interaction does it | 17:38:45 |
@lily:lily.flowers | (I'll admit I really don't feel like bisecting the kernel right now, though, if it does turn out to be a kernel bug) | 17:40:16 |
@gdamjan:spodeli.org | tmpfs /sysroot is too fast, and not the whole PCI is enumerated? | 18:05:23 |
@lily:lily.flowers | Yeah but scripted stage-1 should be loading 9pnet_virtio on-demand too. Let me try introducing a wait between sysroot.mount and the 9pnet mounts | 18:07:26 |
@gdamjan:spodeli.org | I don't think async PCI is on the mind of many people :D | 18:07:59 |
@lily:lily.flowers | I suppose? Let me actually just introduce a sleep before sysroot.mount then. PCI should be settling before then anyway, but that would at least show that it's not just that the bootup is too fast | 18:09:27 |
