Hello guys,
I applied the 3 patches about ubifs support on kirkwood successfully.
Many thanks Daniel
I am using linux kernel 2.6.37.6 and mtd-ults 1.4.5.
When erasing, flashing and mounting the first time with mtd-utils from
an initramfs openwrt , it goes well.
After some umount/mount sequences, I often get many messages about
torture test for PEB, that take 100% of the CPU, like those:
> UBI: run torture test for PEB 100
> UBI: PEB 100 passed torture test, do not mark it a bad
> UBI: run torture test for PEB 100
> UBI: PEB 100 passed torture test, do not mark it a bad
> UBI: run torture test for PEB 100
> UBI: PEB 100 passed torture test, do not mark it a bad
> ....
> UBI: PEB 100 passed torture test, do not mark it a bad
> UBI: run torture test for PEB 100
> UBI: PEB 100 passed torture test, do not mark it a bad
> UBI: run torture test for PEB 100
Does any know how to solve this issue?
May be the ubo and ubifs code has some bug in kernel 2.6.37.6...
Here is a full history case:

Bug easy to reproduce from a initramfs.
Any idea ?
