Public bug reported:
This isn't a bug just in the Ubuntu kernel, as it happened on Debian
too, and I wouldn't rule out any hardware issue either, but I wanted to
share this here to see if I could get any help. I dual boot Windows and
Linux and I think my WiFi card might be failing, but it could also be a
case of bad firmware. It used to work well, but now both Windows and
Linux fail to start my card most of the time. However, sometimes Windows
will successfully be able to use it.
This is the latest bit of error lines that have appeared in dmesg:

Looking at the original error and the files in the kernel, it appears in
iwl_trans_pcie_grab_nic_access, the firmware uses iwl_poll_bit to read
from one of the device's registers, but that times out. It then tries to
dump this error with iwl_mvm_dump_lmac_error_log, but that fails too, as
it needs to access the device's SRAM. So it appears the memory on the
device is inaccessible. Is the indicative of hardware failure, or is it
possible to use setpci to fix the device, as that is one possible
solution I found, but it mentioned a different card model.
