Message: 91714

I compiled bfn5xx_nand as a moudle on bf527-ezkit.

when I loaded it using "modprobe bf5xx_nand" ,it worked well ,but when I unloaded it and then reloaded it ,i got messages below

you want to get the 2009R1 svn branch and replace the linux-2.6.x directory with that

rm -rf linux-2.6.x

svn checkout svn://sources.blackfin.uclinux.org/linux-kernel/branches/2009R1 linux-2.6.x

Maybe my hardware has some problem,I've solved this by removing the bfin_rtc temporarily.

So I can test the nand flash controller driver,but It still cannot work.

are you using SLAB, SLOB, or SLUB as your allocator ?

I've test all of these allocators ,whicherver allocator i use ,i can't repeat the load-unload operation more than twice.

Is it a bug that has not fixed? if it is so ,i'll change my solution to prevent reloading.
