I have tried this diff on r331284 and it still panic when I plug my Transcend microSD reader in. The stack backtrace is exactly same with what I've supplied in the mailing list.

Refrain from using hard-coded length value, part 2.

Refrain from using hard-coded length value; per the advice from @ian.

Forgot to make cpu_model as static.

Use existing CPU detection in sys/arm/arm/identcpu-v6.c.

Also, as @andrew and @ian suggested, I am thinking about this: first set the OID with what identify_arm_cpu() gives us, then later when FDT is available (inside initarm()?) add the board specific core name to the OID.

I am trying to reuse the existing core detection in sys/arm/arm/identcpu-v6.c:288 for filling out the OID.

Pardon my naive questions; this is my first time handling non-userland code.
