From e009f1b202219c62ea7e277adbb953d703dac983 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 19 Mar 2007 15:31:42 -0400 Subject: UHCI: Fix problem caused by lack of terminating QH This patch (as871) fixes a problem introduced by an earlier change. It turns out that some systems really do need to have a terminating skeleton QH present whenever FSBR is on. I don't know any way to tell which systems do need it and which don't; the easiest answer is to have it there always. This fixes the NumLock-hang bug reported by Jiri Slaby.
