| c_smith | so I've already filed a bug for my issue (regarding ohci_pci dropping 2 specific USB ports) but I'm mainly here to see if I can at least help find a temporary workaround for the issue since booting isn't of help since the issue happens roughly a minute after boot every boot now, I wonder if unloading and reloading the ohci_pci module would help at all and is reasonably safe | 04:27 |
|---|---|---|
| apw | c_smith, normally dropping a module is meant to be safe, worth trying. if you let us know the bug number we might be able to suggest something more | 07:56 |

| smoser | hey. | 13:02 |
| smoser | i'm looking for some education | 13:02 |
| smoser | https://pastebin.canonical.com/166997/ | 13:03 |
| smoser | http://paste.ubuntu.com/23274982/ | 13:03 |
| smoser | that runs in a chroot of one ubuntu release that is not necessarily the same as the host | 13:04 |
| smoser | the chroot doesn't have /lib/modules/$(uname -r). so 'modprobe' will fail to load overlayfs or overlay if you did that. | 13:04 |
| smoser | but somehow 'mount -t overlayfs' gets it mounted | 13:04 |
| apw | smoser, the kernel can load things too | 13:04 |
| smoser | the mount abi call must just ask the kernel to mount of that type, and then the kernel loads it by the fs-NAME alias ? | 13:05 |
| apw | fs/filesystems.c: if (!fs && (request_module("fs-%.*s", len, name) == 0)) | 13:05 |
| smoser | hm.. that sucks. | 13:06 |
| smoser | means that my code that says "can i use overlay" is needing fixing as it relies on being able to load the module or have it in /proc/filesystems already. :-( | 13:07 |
| smoser | apw, so other places i have done in the past 'modprobe nbd' is there any way to get similar behavior for that ? | 13:08 |
| apw | from inside a container, not to my knowledge | 13:09 |
| apw | snapd seems to have to hand it out to snapd itself for execution so i assume not | 13:09 |
| apw | i assume they have found no way to do it | 13:09 |
| apw | smoser, but why do you care? can you not literally mount -t overlay || mount -t overlayfs | 13:10 |
| apw | smoser, or just assume based on version number ? | 13:11 |
| ogra_ | smoser, https://github.com/snapcore/snapd/blob/master/docs/interfaces.md#kernel-module-control ... ? | 13:11 |
| ogra_ | (in case you want to load a module from a snapped up thing) | 13:11 |
| mjg59 | smoser: The only reliable way to determine whether the kernel can do something is to try to do it and see what error you get back | 13:13 |
| smoser | i'd rather not loop over attempts to mount something. | 13:18 |
| apw | then use the kernel version number | 13:18 |
| one|2 | infinity: where is tim? | 13:59 |
| apw | one|2, which tim | 14:00 |
| one|2 | apw: tim working on the kernel | 14:00 |
| * ogra_ guesses tim is at home | 14:14 | |
| ogra_ | (if he doesnt travel that is) | 14:14 |
| apw | one|2, are you asking his timezone or if he is here now, he is here now | 14:17 |
| one|2 | tim the nascar video is still running | 14:36 |
| one|2 | this looks like the oracle kernel | 14:37 |
| one|2 | PaulW2U: hello | 15:12 |
| om26er | jsalisbury, Hi! re: bug 1627108 the first debs that you gave me contain the regression. | 16:56 |
| ubot5 | bug 1627108 in linux (Ubuntu Yakkety) "X1Carbon comes to a crawl during high CPU usage tasks" [High,In progress] https://launchpad.net/bugs/1627108 | 16:56 |
| jsalisbury | om26er, ack, thanks for testing. I'll build the next kernel and post when it's ready. | 16:57 |
| jtaylor | hi, the lts-yakkety kernel (-20) from the dev ppa can't mount my lvm raid1 devices do to unknown compatibility flags, is this a known issue? | 17:21 |
