--- Sonic Zhang 2008-04-15 00:27:30

Can't replicate on 2008R1 branch.

--- Mingquan Pan 2008-04-17 05:55:06

If you run the script that under testsuits/lmbench/lmbench_test.exp which

execute ./lat_ctx with 7 different params,it would be frequently see this issue.

--- Mingquan Pan 2008-12-03 04:10:26

It also happens frequently to bf527 ezkit board.
