Comment 3 Darren Hart 2011-08-30 08:55:54 UTC 
Have you tried with a new boot media device? Seems this could be the result of a failing drive/flash.
Comment 4 Bruce Ashfield 2011-12-15 11:39:02 UTC 
Zumeng: can we test this on the 3.0.x kernel ?
Comment 5 zumeng.chen@windriver.com 2011-12-16 01:47:58 UTC 
Yes, done, it can be reproduced in the 3.0.12. I'll try to fix.
Comment 6 zumeng.chen@windriver.com 2012-03-01 09:24:51 UTC 
Bruce,

I guess we can close this case based on my following comments:

1 ) MIPS flush_dcache_page doesn't cover cache alias effectively, so it can't cure over memory read error when cache alias happened(there is a address band for cache alias more than one page); meanwhile We can't replace flush_dcache_page with flush_cache_range in too low level, I guess there
is heavy performance lose.

2 ) We have two choices:
    a ) Close this case with my fixes, just in mm/msync.c level, we don't care the performance since there is an active sync action.
    b ) Close this case without any touch.

I'm OK for both.

Regards,
Zumeng

The patch has been integrated into standard kernel rspro.
