Lantiq ase based platform soft lockup

Reported by: anonymous Owned by: blogic
Priority: normal Milestone: Barrier Breaker 14.07

Description

As of trunk@33493, in linux-3.3.8/drivers/net/ethernet/lantiq_etop.c:ltq_etop_mdio_rd() the second 'while()' reading LTQ_ETOP_MDIO register hangs in an infinite loop.
It happens after a random amount of time and with no particular system activity.

With the following patch my board (a Sitecom 300n wl-367 v1) is running stable since 6 hrs now

Bit 2 in the CFG register enables an automatic mode for the MDIO operation. It can most likely be turned off all the time.
