From mboxrd@z Thu Jan 1 00:00:00 1970 Subject: 2.5.44-mm2 CONFIG_SHAREPTE necessary for starting KDE 3.0.3 From: Steven Cole Content-Type: text/plain Content-Transfer-Encoding: 7bit Date: 22 Oct 2002 11:01:48 -0600 Message-Id: <1035306108.13078.178.camel@spc9.esa.lanl.gov> Mime-Version: 1.0 Sender: owner-linux-mm@kvack.org Return-Path: To: Andrew Morton Cc: linux-mm@kvack.org List-ID: Greetings all, My experience with 2.5.44-mm2 and KDE 3 runs counter to the experience of some others. I've booted several kernels this morning on my UP test box and found that starting KDE 3.0.3 using XFree86 4.2.1 _requires_ that CONFIG_SHAREPTE=y for my system. All kernels were UP and PREEMPT. With CONFIG_X86_UP_IOAPIC=y and nmi_watchdog=1, the results were the same. If SHAREPTE is not set, then the KDE startup fails with a frozen pointer after the initial dark blue screen changes to black. This does appear to be KDE-related. When Gnome is my default desktop, that works just fine with 2.5.44-mm2 and CONFIG_SHAREPTE not set. Here is a snippet from /var/log/messages. At 09:31:23, I did a alt-sysrq-P. I also did a alt-sysrq-T right after that and that information is available if needed.
