http://bugzilla.opensuse.org/show_bug.cgi?id=1086739 Bug ID: 1086739 Summary: Kernel panic booting install DVD(s): kernel BUG at ../kernel/resource.c:722 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: i686 OS: SUSE Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: hendersm@shaw.ca QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux i686; rv:34.0) Gecko/20100101 Firefox/34.0 SeaMonkey/2.31 Build Identifier: This issue prevents booting the installation disk with DVDs burned from the following ISO images: openSUSE-Tumbleweed-DVD-i586-Snapshot20180213-Media.iso openSUSE-Tumbleweed-DVD-i586-Snapshot20180314-Media.iso openSUSE-Tumbleweed-KDE-Live-i686-Snapshot20180314-Media.iso Each image was verified by sha256sum before burning, and after burning, the original ISO image and the new DVD were both mounted, then compared to each other. All verification was good. Boot fails for any of the options that try to launch a Linux kernel from the DVD, i.e., "Installation", "Upgrade", "Rescue System", or "Check Install Media". The progress box ("Starting...") comes up, runs through "Loading Linux Kernel" to the 100% mark, then the screen blanks momentarily, there is a flurry of boot-progress activity text, then the kernel panic. The entire thing occurs within a couple of seconds of the screen change. Reproducible: Always Steps to Reproduce: 1. Load installation DVD for affected release -- see above. 2. Boot from DVD, and select "Installation" after the initial bootsplash. 3. Wait through the "Loading Linux Kernel" progress dialog. 4. Watch the ensuing system crash. Actual Results: Kernel panic/system crash. Expected Results: Entry into installer screens. This appears to be a regression; I have no problem booting the DVD for the 20170129 snapshot of Tumbleweed (the most recent I have available prior to this). It is also possible, however, that the regression is much more recent; the 20180213 Tumbleweed snapshot (which fails) reports kernel 4.15.2-1, but I am able to successfully boot kernel 4.15.0-10 (from a Kubuntu 18.04-beta1 disk). Other relatively recent kernels (4.12.7, 4.13, and 4.14.12) from various distributions also boot successfully. The target machine is a Toshiba Tecra M5 laptop, model ST8112; I can provide further hardware information as required -- please specify. Of potential interest, however: I have two of these Tecras, almost twins, but one uses an NVidia Quadro NVS 110M/128 MB graphics adapter, and the other has integrated Intel 945GM graphics. The NVidia machine crashes as described here; the Intel one is unaffected, i.e., the above-noted Tumbleweed snapshots boot without incident. Finally, please see the attached file, containing a trace of the kernel panic as dumped to my screen. Hopefully this will be helpful. -- You are receiving this mail because: You are on the CC list for the bug.
