You could try the attached one line patch. Since VAPPEND is a modifier for VWRITE, it makes sense to clear it along with VWRITE, I think? rick Thanks for your help. Unfortunately I can neither comment on the patch, nor reproduce the panic... I tried the patch and all seems fine, but also without the patch (the exactly same kernel some days ago, but machine was rebooted since). Of course, the machine has been rebooted after the panic too, when I was able to reproduce the panic easily. Any idea why the pnaic was once reproducable and now isn't anymore? Of course, _nothing_ was changed since then, besides bootme flag on one GPT partition. 9-beta2 never booted since then... No hardware has changed either !?! *kopfkratz* Thanks, -Harry Here's some LORs, I havenÄt checked if they're already known.
