Subject: iwlwifi: BUG: unable to handle kernel paging request at ffffc90000e1c808
Date: Thu, 11 Apr 2019 23:07:20 +0200 [thread overview]
Message-ID: <20190411210404.GC4743@dhcp22.suse.cz> (raw)
Hi,
I have just encountered the following splat with 5.1-rc4. Is this a
known problem? Greping throug older logs show that "Error sending SCAN_CFG_CMD"
is not new. In older kernels it was followed by "Start IWL Error Log Dump:"
but it oopsed now. I was running 5.0 previously. Let me know if you need
more information.
