Standby/resume omap 5910 board

Hi
I run 2.6.20-rt8 kernel on board like innovator1510 (OMAP5910 cpu) Board enter Deep Sleep mode cleanly, and it is OK, but in resume has a problem. (I use echo -n standby > /sys/power/state command)
When it wakes up, some times I get string:

omapflash.0: Waiting for chip to be ready timed out. Status 3068
Write of 68 bytes at 0x00945628 failed. returned -5, retlen 0
Not marking the space at 0x00945628 as dirty because the flash driver returned retlen zero

Searching in mtd subdir show, that mtd driver has functions suspend and resume (cfi_intelext_suspend() & cfi_intelext_resume()), but both of this functions are not calling in suspend/resume process.
Searching through configs files in omap1 directory does not any shine any lite on this problem.

May be it is pm mail list question, or mtd mail list, but many omap-based device suspend/resume cleanly without such problem, I think. Can anyone help me?
