My GTA04 (mobile phone using OMAP3 and TWL4030 PMIC) has difficulty rebooting
with 3.5.
The first boot (after power on) works fine. But when I reboot it hangs just
before
Switched to new clocking rate (Crystal/Core/MPU): 26.0/332/800 MHz
is printed. If I remove "mpurate=800" from the kernel command line the
problem goes away.
If I boot into 3.5, which works, and then reboot into an older working kernel
it freezes too. So the 3.5 kernel leaves the device in a state which causes
any kernel to hang.
I spent a while bisecting and narrowed it down to
commit f9d29f1617eb1b2f1fd41622bd1a0fc51658d2f0

arm: omap3: voltage: fix channel configuration
If I revert this patch then the problem goes away. So that is the fix I'll
go with for now, but if anyone wants me to try something else to help find
out what the real problem is and to find a proper fix, I'm happy to help.
Thanks,
NeilBrown
