hi, Artem
I found a problem when I test ubifs on unclean reboot,my test method is that:read,write,and delete ubifs files many times , when I'm writing or deleting the files ,I
reboot the system, sometimes the rootfs is broken,but if I reset the power of board,the rootfs is ok.
my environment:
my UBI and UBIFS is porting from linux2.6.38 ,and linux kernel is linux 2.6.35,and use the following seven patches :http://patchwork.ozlabs.org/patch/85935/ .UBIFS is rootfs,
and I make unclean reboot test in /tmp ,my ubi partition size is 450M bytes. flash is a SLC nand flash,flash information is following:
Nand ID: 0xAD 0xDC 0x10 0x95 0x54 0xAD 0xDC 0x10
Nand(Hardware): Block:128K Page:2K Ecc:1bit Chip:512M*1 OOB:64Byte
NAND device: Manufacturer ID: 0xad, Chip ID: 0xdc (Hynix NAND 512MiB 3,3V 8-bit)
I run my ubifs test in background,and wait for random seconds ,then reboot the system, make this many times, then some boards will be error when I reboot the system,the debug
info is following:
delete files
delete 2594 files
write disk 15091695 file 40023umount: tmpfs busy - remounted read-only
