Hi, All
We got following errors on OMAP ES2.0 board.
And noticed a similar case was reported at below link
http://www.opensubscriber.com/message/kernel-t...@lists.ubuntu.com/14591440.html
Is any conclusion/fix available?
<1>[ 348.873840] Unhandled fault: imprecise external abort (0x1406) at
0x4
Tao Hu,
Did you try the similar solution in our Ubuntu kernel? We suspect it
related to HIGHMEM, SMP and cache control code.
And how about your test case?
Thanks a lot,
-Bryan

Hi, Bryan
Thanks.
Unfortunately, it is not easy to reproduce the problem in our HW.
We only observed 2~3 times so far.
But we do enable HIGHMEM, SMP and L2 cache in our config.
That's why I'd like to know the root cause.

Hu Tao,
We hit this issue every time when we build the kernel on the board.
Are you running some stress testing program on the board?
Thanks,
