[BUG bisect] Missing Micrel driver on VF50 (net: phy: check return code when requesting PHY driver module)
From: Krzysztof Kozlowski
Date: Fri Jan 18 2019 - 03:39:46 EST
Hi,
On today's next (next-20190118) my Colibri VF50 board fails to boot up
from network (DHCP, NFSv4 root). Looks like missing network adapter.
Expected:
[ 3.041773] Micrel KSZ8041 400d1000.ethernet-1:00: attached PHY driver
[Micrel KSZ8041] (mii_bus:phy_addr=400d1000.ethernet-1:00, irq=POLL)
Result:
[ 15.614964] Root-NFS: no NFS server address
[ 15.619353] VFS: Unable to mount root fs via NFS, trying floppy.
[ 15.626762] VFS: Cannot open root device "nfs" or unknown-block(2,0): error -6
[ 15.634252] Please append a correct "root=" boot option; here are the
available partitions:
