Hi guys,
I just tried today's Linus' master (45f7fdc2ff) with usb-linus (3635c7e2d5)
merged on top to give the latest dwc2 fixes another try.
Unfortunately I'm getting various crashes on system startup. Kernel boots
fine, dwc2 and the integrated smsc95xx are detected, but somewhere in the
init sequence the system panics.
I haven't ever seen crashes like that, when running linux-next. I also
merged those two exact commits together and didn't see any issue in 10
boot cycles.
Same thing here with linux-next (Linux rpi 3.14.0-rc2-next-20140213-rpi).
The last traces has systemd in there, but good old sysvinit crashed
spectacular too.
FWIW, I am running:
* A rev2 Model B
* Firmware commit 9c3d7b6 "Add latest linaro gcc toolchain:
gcc-linaro-arm-linux-gnueabihf-raspbian-2012.08-20120724_linux"
* Upstream U-Boot (very recent) and kernel
* Using Ubuntu 13.10's packaged ARM cross-compiler
Huh, switching compilers made a difference...
I was using debian's cross compiler [0], 4.8.2, which has a couple of
patches [1].
With my old self compiled and unpatched toolchains I didn't yet get
any crashes, I tried:
binutils 2.20 + gcc 4.4.4
binutils 2.21.1 + gcc 4.4.7
binutils 2.23.1 + gcc 4.7.1
binutils 2.24 + gcc 4.7.2
but with these versions (also unpatched) I do get the crashes:
binutils 2.23.2 + gcc 4.8.1
binutils 2.24 + gcc 4.8.2
I saw problems with 4.8 on NetBSD/evbarm and my RaspberryPI. They were
fixed by changes to the gcc-4_8-branch some time after 4.8.2.
