Bug#767042: [jessie daily 2014-10-27] [armhf] Installation report: LeMaker Banana Pi - problems with autoloading the realtek ethernet PHY driver module
Package: installation-reports
Boot method: hd-media (installer booted from USB stick)

Date: 2014-10-27
U-Boot: 2014.10+dfsg1-1
Machine: LeMaker Banana Pi
Processor: Allwinner A20 (2x Cortex A7)
Memory: 1GB
Mass Storage: 16GB SD card
Base System Installation Checklist:
[O] = OK, [E] = Error (please elaborate below), [ ] = didn't try it
Initial boot: [O]
Detect network card: [E] (see comments below, getting this to work
requires manual loading of the proper
ethernet PHY driver module)
Configure network: [O]
Detect CD: [O]
Load installer modules: [O]
Detect hard drives: [O]
Partition hard drives: [O]
Install base system: [O]
Clock/timezone setup: [O]
User/password setup: [O]
Install tasks: [O]
Install boot loader: [O]
Overall install: [O]
Comments/Problems:
The "detect network hardware" step fails with
"No Ethernet card was detected. If you know the name of the driver
needed by your Ethernet card, you can select it from the list."
dmesg shows:
[ 73.100072] stmmaceth 1c50000.ethernet: no reset control found
[ 73.100103] Ring mode enabled
[ 73.100112] No HW DMA feature register supported
[ 73.100120] Normal descriptors
[ 73.100127] TX Checksum insertion supported
[ 73.104782] libphy: stmmac: probed
[ 73.104812] eth0: No PHY found
i.e. the correct ethernet MAC driver (stmmac) gets loaded
automatically, but the necessary PHY driver (realtek) does not.
Loading the realtek module after the stmmac driver has probed
for a PHY does not change anything; the stmmac driver does not
re-probe for a PHY upon later loading of the PHY driver.
Manually unloading the stmmac module, loading the PHY driver
and then loading the stmmac module again from a shell by
running
~ # rmmod stmmac
~ # modprobe realtek
~ # modprobe stmmac
results in
[ 499.364044] stmmaceth 1c50000.ethernet: no reset control found
[ 499.364076] Ring mode enabled
[ 499.364084] No HW DMA feature register supported
[ 499.364090] Normal descriptors
[ 499.364097] TX Checksum insertion supported
[ 499.392561] libphy: stmmac: probed
[ 499.392592] eth0: PHY ID 001cc915 at 0 IRQ POLL (stmmac-0:00) active
[ 499.392604] eth0: PHY ID 001cc915 at 1 IRQ POLL (stmmac-0:01)
and the ethernet interface works. The kernel version used in this
installer build is 3.16.5-1.
