Hi Felix,

do you have CONFIG_NO_HZ defined ?

I've seen similar problems with powerpc + CONFIG_NO_HZ. In my case the 
low-level
do_write_buffer (cfi_cmdset_0002.c) timed out too early. See
http://lkml.org/lkml/2009/9/3/84

Maybe in your case it's the do_erase_chip timing out too early.

Thanks for suggestion.

I have CONFIG_NO_HZ defined, but disabling it doesn't help.
I my case timeouts occur in NAND driver, fsl_elbc_nand.c
