Dear Chris, Thanks for your testing and feedback. Apologies about the patch being insufficient. I have not had access to the affected hardware since my previous post.
I note work continues at Fedora on this bug which can be found at: https://bugzilla.redhat.com/show_bug.cgi?id=812651 Instead of the insufficient patch a possible test which could be tried is altering line 37 of the debian/rules file to include CFLAGS += -O2 -fno-tree-dce -fno-optimize-sibling-calls This would follow from the information suggested by Fabrice Bellet on the Fedora bug list. This is both a bit of a hack and shot in the dark since I don't own the hardware to test. I might get access to the hardware this weekend though. best regards, Peter
