Seems this could be the result of a failing drive/flash. 17675 4 bruce.ashfield 2011-12-15 11:39:02 +0000 Zumeng: can we test this on the 3.0.x kernel ? 17700 5 zumeng.chen 2011-12-16 01:47:58 +0000 Yes, done, it can be reproduced in the 3.0.12. I'll try to fix. 18822 6 zumeng.chen 2012-03-01 09:24:51 +0000 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 19368 7 zumeng.chen 2012-03-23 01:06:34 +0000 The patch has been integrated into standard kernel rspro. 19749 8 yi.zhao 2012-03-31 10:19:08 +0000 Verified with 1.2 RC1 20120328 build.
