Well, the day before yesterday I built the fglrx-modules for linux-rt, but now each time I try to use ardour it disconnects after a few minutes with the message that jack disconnected ardour for not being fast enough. Each time my whole system hangs for a few seconds, and cpu load is reported to be "e+02", e.g. 100% in qjackctl. Now dmesg tells me: "[ 1950.955240] ACPI Exception (evregion-0419): AE_TIME, Returned by Handler for [EmbeddedControl] [20080609] [ 1950.958786] ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.BAT1._BST] (Node f74284dc), AE_TIME" Well I guess I can live with that one. But later on it says something like "[ 2027.967536] ardour-2.7.1[7399]: segfault at 2e454467 ip b7e52000 sp b23cf3c0 error 4 in libardour.so[b7d1c000+294000]" and "...

Obviously ardour and fglrx don't get along. So is there any way to fix this? At the moment ardour is unusable for me, so I'd really appreciate any suggestions!
