This bug affects me too. Hardware is exactly the same. Dell XPS 13 9350 We have two places to fail here, linux-firmware and kernel. Tried different version combinations upgraded\downgraded. Last working kernel for me is 4.18.16-300.fc29.x86_64 #1 SMP Sat Oct 20 23:24:08 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux No issues with this kernel with any linux-firmware package. Kernels greater than this one break my wifi on regular basis. ```[14553.667734] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14553.667742] brcmfmac: brcmf_cfg80211_get_station: GET STA INFO failed, -5 [14555.715751] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14557.763741] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14557.763748] brcmfmac: brcmf_cfg80211_get_station: GET STA INFO failed, -5 [14559.811660] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14561.859709] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14561.859716] brcmfmac: brcmf_cfg80211_get_station: GET STA INFO failed, -5 [14563.908605] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14565.955611] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14565.955623] brcmfmac: brcmf_cfg80211_get_station: GET STA INFO failed, -5 [14568.003577] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14570.051608] brcmfmac: brcmf_msgbuf_query_dcmd: Timeout on response for query command [14570.051614] brcmfmac: brcmf_cfg80211_get_station: GET STA INFO failed, -5 ``` Workaround is to stick to 4.18.16-300.fc29.x86_64 kernel. (In reply to Artem Silenkov from comment #1) > Workaround is to stick to 4.18.16-300.fc29.x86_64 kernel. So this first breaks with 4.18.17? : https://koji.fedoraproject.org/koji/buildinfo?buildID=1160572 Or did you not test that one ? If this broke between 4.18.16 and 4.18.17 it should be relatively easy to figure out what broke it. Nope didn't test this one. / ❯❯❯ dnf list installed "kernel-core" Installed Packages kernel-core.x86_64 4.18.16-300.fc29 @anaconda kernel-core.x86_64 4.19.7-300.fc29 @updates kernel-core.x86_64 4.19.8-300.fc29 @updates Fedora installer ships 4.18.16-300 <- good one And updates repo goes directly to 4.19.7-300 <- broken. The problem is this thing is hard to reproduce. It is just happening randomly even when laptop is completely idle. Will do testing with 4.18.17 tomorrow.

Kernel v4.18.17 works for me, no wifi issues. Further switching to 4.19.7 triggers errors. I'm trying to bisect kernel sources to figure out offending commit but there are so many changes I feel lost already. Created attachment 1514631 [details]
Full dmesg from boot to wifi fail
kernel 4.19.8-300.fc29.x86_64
full dmesg from fresh boot to wifi fail.
Comment on attachment 1514631 [details] Full dmesg from boot to wifi fail Crosspost from kernel.org bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=201853 New update kernel=4.19.10-300.fc29.x86_64 is still bugged. Sadly I need fresh kernel for development tasks and this bug breaks core functionality for me. iw dev wlp58s0 set power_save off Could do the workaround but not good for battery which is terrible when travelling. Thank you for the bug report, I've send an email to the upstream brcmfmac maintainers asking them for help with this. *********** MASS BUG UPDATE ************** We apologize for the inconvenience.
