[ECOS] JFFS2 Access and interrupts

Hi all,

while writing a file in a jffs2 filesystem (by means of open, write,
my application seems to hang in function write(). 
After guarding the write access with
the write accesses worked properly.

After a short inspection of flash.c (in packages/io/flash/current/src)
it seems that in my port these guards are already present,
placed around the "__anonymizer"-ed flash access functions.

Is there a general rule, how to handle mutual IRQs and flash access ?
Do I miss something ?
Is there a configuration option, I've forgotten to enable ?

Kind regards,
Gernot Zankl

Btw: PowerPC MPC5200B and external flash Spansion S29GL064M
