hi everyone,
I m using custom board similar to MPC8272ADS board...
1) For the first time it boots up properly in case if we overwrite any
existing binaries using nfs mounted file system on the board, after
rebooting it displays fallowing message...
Further such events for this erase block will not be printed
Eep. Child "null" (ino #1346) of dir ino #3 doesn't exist!
Eep. Child "autocomm" (ino #463) of dir ino #461 doesn't exist!
Eep. Child "calibration" (ino #464) of dir ino #461 doesn't exist!
Eep. Child "coredsp_driver.ko" (ino #939) of dir ino #336 doesn't exist!
Inode #1307 was a directory with children - removing those too...
Inode #564 was a directory with children - removing those too...
Inode #565 was a directory with children - removing those too...
Inode #1112 was a directory with children - removing those too...
Inode #1115 was a directory with children - removing those too...
Inode #1118 was a directory with children - removing those too...
Inode #1123 was a directory with children - removing those too...
after this board boots up properly....but it not be having overwritten files
2) while booting up for the first time itself it will display the falowing
message..
modprobe: FATAL: Could not load
/lib/modules/2.6.10_mvl401-8272ads/modules.dep: No such file or dire
ctory
but after this also board boots up properly
3) when board is running properly in between it starts printing on console
repeatedly...

Are you using a non-standard flash SIMM? The one that comes with the
board (that I've seen, at least) have interleave 4, and are mapped at
0xfe000000.
Was it the physmap driver or the pq2fads driver that found the flash?
Which kernel are you using, and are you using arch/ppc or arch/powerpc?

which are all the most possible reasons for these errors ?

First of all this is CUSTOM board similar to MPC8272ADS.
We are using flash which is different from flash that comes with the
MPC8272ADS board.
FLASH: S29GL256N90TF
Total size is 64 MB with 2 flash interleave
mapped at 0xfc000000.
>>Was it the physmap driver or the pq2fads driver that found the flash?
Flash is cfi compatible.
>>Which kernel are you using, and are you using arch/ppc or arch/powerpc?
>> -Scott
KERNEL: linux-2.6.10 and we r using arc/ppc

Most common is making a jffs2 filesystem with the wrong block size. It
could also be an incorrect flash mapping.

That's not what I meant... you have two mapping drivers enabled, and
the pq2fads driver might be doing something other that what you
specified to physmap. I'd just disable it.

That's pretty old... If all else fails, you may want to see if never
kernels still have the problem.
