Title:
iwlwifi/iwlmvm & Intel 9260 [8086:2526] subsystem [8086:0014] made
kernel unstable since 4.15.0-91
Status in linux package in Ubuntu:
Expired
Bug description:
My home server/router/access point runs under Ubuntu 18.04.4 with all updates
and has 2 wifi adapters operated by hostapd
one is USB AR9271 (0cf3:9271, driver ath9k_htc), another is PCIe Intel AC
9260 (8086:2526, driver iwlwifi).
with kernel 4.15.0-88 it worked quite stable, with reboots required mostly
after kernel upgrades (much less frequent reboots due to panics)
with kernel 4.15.0-91 and -96 it started rebooting by itself by panic when a
lot of activity happening via Intel 9260.
In /etc/sysctl* I have kernel.panic=10 , kernel.softlockup_panic=1 and
kernel.panic_on_oops=1 overrides of default values.
In dmesg logs preceding the reboot, I see multiple warnings with stacks
inside iwl_mvm functions which I could provide by apport. Also, multiple
messages like "Command LQ_CMD: a command is already active!" or "Error sending
LQ_CMD: time out after 2000ms"
Unfortunately I run this box headless and I don't have another wired Ethernet
host to capture its panics by netconsole
The rest of hardware is pretty standard. Asus B85M-G mobo, Core i3-4130T CPU,
nothing overly special.
More details I would provide in your further requests but the current kernel
behavior is very annoying.
