Not repeatable, but it crashed once when unmount the vfat partition.

--- Vivi Li 2011-09-21 04:11:39

Crashes don't only happen with dd command.

It can happen any time when operates MMC.

--- Vivi Li 2011-09-21 04:44:54

I attach my configuration for your reference.

--- steven miao 2011-10-20 06:31:13

Not repeatable in my bf518 board, I'll try another board

--- Vivi Li 2011-10-21 02:34:14

Please try to test in board on regression machine 10.99.29.80.

--- steven miao 2011-10-28 03:11:12

can repeatable now, probably happens when slab reap

--- Sonic Zhang 2011-11-03 06:28:00

The crash disappears after update to kernel 3.0.8.

Case 27 failure is fixed by limit mmc dma segment len for bf518.

Should add rootwait to mmc boot args in test suites as well.

--- Vivi Li 2012-06-05 04:30:29

rootwait is added to test script.

Close this bug.
