Hi,

I've been running a kernel with both of the suspend fixes (pause TCM on
fast resume, cleanup IWL_MVM_STATUS_IN_HW_RESTART in resume) here for
the last few days. I just experienced this fault - not from
suspend/resume this time though, the laptop wasn't doing anything
particular at the time, so no idea how to reproduce it.
Maybe it's related though (?) as it has the same
"Error sending SYSTEM_STATISTICS_CMD: time out after 2000ms."
It recovered ok, wifi was functional afterwards.
