Occasionally (especially after a reboot), the kernel will fail to boot with a
"TWL4030 module irq 370 is disabled but can't be masked!"
Comments (Richard Woodruff)
This issue likely comes from a missing sequence script for T2. If you do a warm
reset (from reboot command) or a watchdog resets you, T2 is not automatically
reset. If CPUFREQ is running you also may find your boot fails altogether as
with out a reset of T2 voltage may be too low as compared to what boot code
T2 internally has some sram. You need to program into T2 what action to take
when it sees a reset. Code is about in the 2.6.24 kernel which needs to be
ported over apparently.
