Bug: Flash writing & suspending

Oh, BTW, the same error happens also on:

a) plain 2.6.13-rc2
b) 2.6.13-rc2 with both MTD and JFFS2 from CVS (using the ./patchkernel.sh)

The reason I just installed (manually) the MTD stuff only has to do with a 
suspicion about the problem source.

I suspect that maybe MTD is writing data into the StrataFlash. While this 
erasing & writings happens, it probably polls the built-in state-machine 
status of the chips. Probably during such an operation the suspend-to-memory 
takes place. The hardware switches off the power to the StrataFlash, but MTD 
doesn't know about this.

At resume time, the StataFlash get's power and resets to some initial state. 
Linux thaws the processes, among them the JFFS2/MTD thread. Which continues 
to poll the StrataFlash, but because it has been resetted in the meantime ...
