This isn't ext3 related and I'm fairly certain drivers/net/atl1 is trashing... something. Perhaps the page table because: [ 153.785325] Bad page state in process 'scp' [ 153.785327] page:ffff81000308d020 flags:0x0040ad41dc050845 mapping:53dfe57d17cc59cf mapcount:16885953 count:292554304 [ 153.785329] Trying to fix it up, but a reboot is needed This one dismisses a reference counting issue because the page data here looks like garbage.

My apologies, I had thought the etiquette was to only include maintainers on the CC list. I'll try and locate a maintainer for the Attansic driver a bit later, but I've only seen people loosely related to it. In any case we may as well let this thread die because it's not related to a filesystem bug (which the CC list is presumably interested in). -- Jay L. T.
