Public bug reported:
Intel Wireless-AC 7260 (rev bb) wifi card crashes randomly.
Sometimes after 1h of using my laptop, and sometimes after resuming from sleep.
It can't work again until I reboot my laptop.
The most relevant error message is:
sty 25 14:42:13 leetbook kernel: iwlwifi 0000:25:00.0: Failed to wake NIC for
hcmd
sty 25 14:42:13 leetbook kernel: iwlwifi 0000:25:00.0: Error sending
STATISTICS_CMD: enqueue_hcmd failed: -5
I'm using Ubuntu 20.04 that was upgraded from 18.04 and earlier 16.04.
I've searched for similar bugs, but it looks like my error message and card
model is a bit different.
The workaround script from bug 1673344 works to fix the wifi without rebooting.
The card works fine in Windows 10 so it's not a hardware issue.
This is not a stock card from HP EliteBook 8470w, I've replaced it to gain Wifi
802.11ac transfer speeds.
