Subject: macb: inconsistent Rx descriptor chain after OOM
Date: Mon, 16 Sep 2019 09:41:26 +0200 [thread overview]
Message-ID: <mvm4l1chemx.fsf@suse.de> (raw)
When there is an OOM situation, the macb driver cannot recover from it:
[245622.872993] macb 10090000.ethernet eth0: Unable to allocate sk_buff
[245622.891438] macb 10090000.ethernet eth0: inconsistent Rx descriptor chain
After that, the interface is dead. Since this system is using NFS root,
it then stalled as a whole.
Andreas.
