[Bug 571857] Re: Microcode SW error detected. Restarting 0x2000000 on Intel Wifi 6000

[Jamie Strandboge]

A little more information:

The following bugs indicate this may be a firmware issue when using hwcrypto with the 4965:

Updating to use swcrypto=1 does not prevent the error and fiddling with
the power settings as suggested in the fedora does not help either.

To try swcrypto=1, I did:
$ cat /sys/bus/pci/drivers/iwlagn/0000\:02\:00.0/driver/module/parameters/swcrypto
0

Added the following to /etc/modprobe.d/iwlagn.conf:
# https://bugs.launchpad.net/ubuntu/+source/linux/+bug/571857
options iwlagn swcrypto=1

Then did:
$ sudo rmmod iwlagn
$ sudo modprobe iwlagn
$ cat /sys/bus/pci/drivers/iwlagn/0000\:02\:00.0/driver/module/parameters/swcrypto
1
