Comment 1 Dave Jones 2011-07-11 22:08:26 UTC

we took a pagefault while unmounting, and things went south.
Eric, any ideas ?

Comment 2 Dave Jones 2012-04-11 15:11:13 UTC

Matthew, have you seen any reoccurance of this on a recent kernel ?

Comment 3 Matt Hooper 2012-04-16 18:40:19 UTC

No, but I believe all of my systems are now ext4 based so can't confirm that a newer kernel has fixed this specific ext3 issue. Sorry.

Comment 4 Josh Boyer 2012-04-16 18:54:06 UTC

Thanks for letting us know.
