Re: unionfs kernel panic on 7.1-PRERELEASE
Did you have any ideas where the root of this problem may lie Kostik? - Original Message - From: Steven Hartland [EMAIL PROTECTED] Yes every time, I've got a half life 2 dedicated install mounted under unionfs:- mount -t unionfs -o noatime -o below /usr/local/games/hl2ds /usr/local/games/servers/1 As soon as I start the server from under servers/1 the machine panics I'm thinking its a combination of the Linux ABI and unionfs interaction which is causing the issue.
