[11:29] <freemangordon> Hi guys, starting with kernel version 5.3.0-59.53 on ubuntu 18.04, my atheros wireless dongle stopped functioning - kernel oops, see https://pastebin.com/X5QNS3kZ. oops is on https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/eoan/tree/drivers/net/wireless/ath/ath9k/htc_drv_init.c?h=master-next&id=30da5834ebc404b6bdb8cbcbea99bb5813e4dfcb#n945 . I bisected to https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/eoan/comm
[11:30] <freemangordon> Putting printk("%px", priv); to print that priv variable *fixes* the issue, so it seems to be gcc bug
[11:31] <freemangordon> now, I am stuck, as I have no idea how am I supposed to report such kind of issue
[11:51] <jeremy31> freemangordon: uninstall the iwlwifi backports
[12:05] <freemangordon> jeremy31: already uninstalled
[12:06] <jeremy31> freemangordon: have you rebooted since?
[12:07] <freemangordon> jeremy31: come on, did you look at what I have posted ^^^? I did "git bisect" over ubuntu kernel tree...
[12:07] <freemangordon> ofc I have rebooted, how am I supposed to "git bisect good/bad" without it
[12:08] <jeremy31> freemangordon: I think the 5.3 kernel is EOL
[12:08] <freemangordon> jeremy31: it is not the kernel, but gcc
[12:08] <freemangordon> adding a simple printk() fixes the issue
[12:09] <freemangordon> also, I don;t understand how is 5.3 EOL is if is part of LTS HWE
[12:09] <freemangordon> *if it is
[12:09] <jeremy31> freemangordon: 5.3 is only supported as long as Ubuntu 19.10
[12:10] <freemangordon> ok, but again - this looks like gcc bug, not kernel
[12:11] <freemangordon> and that gcc bug may as well affect other kernel versions
[12:11] <jeremy31> freemangordon: I have a USB wifi with same ID and I used it during Ubuntu 20.04 install
[12:12] <jeremy31> your next updates should include the 5.4 kernel
[12:13] <freemangordon> are you sure? could you please share a source?
[12:15] <freemangordon> also, if it is gcc bug, how moving to 5.4 will fix the issue?
[12:15] <jeremy31> It might be later as linux-generic-hwe-18.04 still shows a 5.3 kernel
[12:16] <freemangordon> exactly
[12:16] <tomreyn> only on bionic, though
[12:17] <jeremy31> https://wiki.ubuntu.com/Kernel/RollingLTSEnablementStack#Kernel.2FSupport-1.A18.04.x_Ubuntu_Kernel_Support
[12:18] <freemangordon> so, you mean that on august there will be upgrade to 5.4?
[12:19] <tomreyn> there is 5.4 already in proposed
[12:20] <tomreyn> Package: linux-image-generic-hwe-18.04
[12:20] <tomreyn> Version: 5.4.0.42.46~18.04.35
[12:20] <tomreyn> Source: linux-meta-hwe-5.4
[12:21] <tomreyn> and then there is -hwe-edge, too, if you want to live on the edge
[12:21] <freemangordon> I don't (want to live on the edge), that's why I am on LTS
[12:22] <freemangordon> this is a 'production' laptop
[12:22] <tomreyn> yes, i should not have treated your report as a support request, since you're clearly trying to solve the root cause, sorry.
[12:23] <freemangordon> tomreyn: ok, so your advice is to not waste time filling bug reports/sending patches and to live with my locally patched ath9k_htc.ko until there is a new kernel release?
[12:24] <freemangordon> yes, I don;t really need support, but rather an advice on what to do with the issue investigation/results I have gathered so far :)
[12:24] <tomreyn> my advice is: if you're trying to solve a bug, report a bug (after looking for duplicate reports), and provide the info needed to analyze the bug.
[12:26] <jeremy31> I am online now with the same wifi and kernel 5.3.0-62
[12:26] <freemangordon> jeremy31: so?
[12:27] <tomreyn> by the way, your first message on this channel was cut off after "I bisected to"
[12:27] <freemangordon> ah, sorry
[12:27] <freemangordon> tomreyn: ...I bisected to https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/eoan/commit/?h=master-next&id=04a29b0362f0ddaf6e8e489a1be5643362bc66ae, which doesn't make sense ...
[12:28] <freemangordon> seems release/version change somehow broke it
[12:29]  * tomreyn can't help with analyzing the bisect, not an ubuntu kernel developer / packager
[12:29] <freemangordon> jeremy31: the fact that it works on your system doesn't mean I don;t have oops here every time I attach the dongle
[12:30] <freemangordon> yeah, lets hope some of the ubuntu kernel devs appear, will try to raise a bug in the meanwhile
