Bug: Flash writing & suspending

[Holger Schurig <hs4233@mail.mn-solutions.de>]

Hi !  I get the above error message sometimes when I write to the flash.

I use Kernel 2.6.13-rc2, but with the MTD (drivers/mtd/, include/mtd, 
include/linux/mtd) from today's CVS. JFFS2 is still the old one.

 partitions are

I wrote a little tests script which can trigger the error:

----------------------------------------------
#!/bin/sh
cd /tmp
for i in 0 1 2 3 4 5 6 7 8 9; do
        logread >log$i.txt
done

for i in 0 1 2 3 4 5 6 7 8 9; do
        rm -f /opt/mn/log*.txt
        cp log*.txt /opt/mn
done

ls /opt/mn/

echo mem >/sys/power/state

ls /opt/mn/
----------------------------------------------

Now I run this script, resume by pressing a key, run it, resume, run it etc. 
Sometimes at the first run, sometimes at the second or third I get this 
error:

Flash: Waiting for chip to be ready timed out. Status 913ad69c
Write of 48 bytes at 0x01db67b4 failed. returned -5, retlen 0
Not marking the space at 0x01db67b4 as dirty because the flash driver returned 
retlen zero

error -5 reading node at 0x00890c44 in get_inode_nodes()
jffs2_get_inode_nodes() for ino 1086 returned -5

So, where is the culprit?
