UBIFS problem on MPC8536DS

Thu Oct 15 05:54:58 EDT 2009

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.
