Subject: macb: probe of 10090000.ethernet failed with error -110
Date: Wed, 28 Nov 2018 11:10:50 +0100 [thread overview]
Message-ID: <mvmefb5fr6d.fsf@suse.de> (raw)
The PHY probing of the macb driver appears to be rather unreliable.
Most of the time it doesn't work the first time, I have to reload the
module several times to let it succeed.
[ 40.530000] macb: GEM doesn't support hardware ptp.
[ 40.530000] libphy: MACB_mii_bus: probed
[ 41.450000] macb 10090000.ethernet (unnamed net_device) (uninitialized): Could not attach to PHY
[ 41.510000] macb: probe of 10090000.ethernet failed with error -110
[ 1354.400000] macb: GEM doesn't support hardware ptp.
[ 1354.410000] libphy: MACB_mii_bus: probed

This is 4.20-rc4 on a HiFive-U.
