This bug is caused by Robin's commit 6969 to kernel 2009R1 branch.

Add wordaround for ANOMALY_05000189 - which should fix bug [#5129]

Works without issues for me!

I wonder if you use a BF537-STAMP with the SCKE Pull-Down installed?

All testing with suspend mem on BF537/6/4 BF52x BF51x BF561 require the

Pull-Down on SCKE.

--- Vivi Li 2009-07-20 06:39:15

So you mean that I should do the similar fix to nearly all the boards as in bug

[#5327]?

Without SCKE Pull-Down installed, suspend to mem will act very strange or it

won't work at all?

--- Michael Hennerich 2009-07-21 03:29:58

All boards that doesn't already feature the Pull-Down on the SCKE strobe

require this resistor, when you re going to test Hibernate/suspend mem.

As far as I know only the latest BF518-EZBRD has this resistor

populated.

Not having it will cause random failures after return from suspend mem,

due lost data integrity in the SDRAM.

-Michael

--- Vivi Li 2009-07-31 06:00:49

It's OK now after a pull down resistor is added.

Close this bug.
