Error message in logs on ASR903 with IOS XE 3.9.0

Hi all,

I have the following error message in logs on our ASR903 running IOS XE 3.9.0 :

Jul 10 10:01:34.273 EET: %IOMD_IMFPGA-3-MDIO_WRITE: SIP1: iomd:  An MDIO write has failed for addr: 0 reg: 1f data: 0

Jul 10 10:03:58.281 EET: %IOMD_IMFPGA-3-MDIO_READ: SIP1: iomd:  An MDIO read has failed for addr: 0 reg: 1

Jul 10 10:04:11.281 EET: %IOMD_IMFPGA-3-MDIO_READ: SIP1: iomd:  An MDIO read has failed for addr: 0 reg: 1

Jul 10 10:04:18.281 EET: %IOMD_IMFPGA-3-MDIO_READ: SIP1: iomd:  An MDIO read has failed for addr: 0 reg: 1

Jul 10 10:04:26.281 EET: %IOMD_IMFPGA-3-MDIO_READ: SIP1: iomd:  An MDIO read has failed for addr: 0 reg: 1

Jul 10 11:46:16.627 EET: %IOMD_IMFPGA-3-MDIO_WRITE: SIP1: iomd:  An MDIO write has failed for addr: 0 reg: 1f data: 204

Any idea what this message could mean and if there is any workaround?

I found a BUG but it's not well documented :

CSCuf05039

Symptom: I2C-WRITE and MDIO_READ error messages are displayed on the Cisco ASR903 router.

Conditions: This issue occurs after an interface module hard or soft OIR is performed.

Workaround: There is no workaround.
