I'm implementing snapshot boot for OSK5912 target.

It's basically extract system snapshot image, do init/setup at uboot,
and jump to kernel resume entry point.

Detail here:

Currently, I get this message from linux:
 * * *
waiting for erase at 00240000 to complete timed out. status = 0, Xstatus = 80.
mtdblock: erase of region [0x0, 0x20000] on "filesystem" failed
end_request: I/O error, dev mtdblock3, sector 256
 * * *
(apart from this, prompt is shown, command gets executed, and ping/telnet
from host is working fine.)

read/write from/to flash is working in uboot, (md.[bwl], mw.[bwl]),
so what is linux complaining?

Can someone tell me, is linux doing additional setups for cfi flash?

Thanks in advcance.
