FWIW, I have a system here where I see similar things; after sufficient uptime it shows an impressive number and proportion of checksum errors (50% or more of the hits, eventually), since at least sometime last fall. No indication anywhere else of problems (CAM, SMART, zpool status). Haven't tried the patches. It would take most of a month of seeing nothing to have much confidence they did anything anyway; it's got >2 weeks now and only ~500 errors, so it takes a long time with this system/workload to ramp up. But it'd be a nice fix to have, so mark me up as a user-vote for landing if the code makes sense to the codesense people. -- Matthew Fuller (MF4839) | fulle...@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
