I guess this means you run with the SMP patches from OpenWRT,
while upstream only supports uniprocessor mode and presumably doesn't
have this problem, right?
I see that Oxnas (supported in OpenWRT but not upstream) has the
slightly newer ARM11mpcore variant 0 / revision 5 ID. Is it easy for
you to test if this has the same problem?
Interestingly, the documentation at http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/I65012.html
lists variant:0/revision:4 as the reported values for both r2p0 and r1p0
and it does not list any core having variant:0/revision:5.
