Good news, and bad, kernel-xen-2.6.17-1.2647.fc6 booted but randomly crashes. Sep 19 10:10:14 localhost kernel: <1>Fixing recursive fault but reboot is needed! Sep 19 10:10:15 localhost kernel: Trying to vfree() nonexistent vm area (ffffc200000d4000) Sep 19 10:10:15 localhost kernel: BUG: warning at mm/vmalloc.c:329/__vunmap() (Not tainted) Created attachment 136594 [details]
Entries from /var/log/messages file showing kernel errors.
As 2.6.17-1.2630.fc6 actually boots I'll close this ticket and open another for crashing problems under 2647. Just tested kernel-xen-2.6.18-1.2693.fc6 and it fails to boot at all. Just past the USB, UHCI initialization I get : "GSI 21 sharing vector 0xc8 and IRQ 21" then nothing, just waits until I power cycle. From your last update to bug 207432, it appears that you are still getting the change_page_attr() BUG()s during boot. It may well be that the graphical boot is crashing as soon as it tries to start X; can you try booting without the "rhgb" option and see if that helps? Interesting, while my results were not improved I observed two interesting things : First, when attempting a cold boot ( from full power off ) I get the "GSI 21 sharing vector 0xC8 and IRQ 21" error/hang. But when I warm boot (CTRL-ALT-DEL) this does not happen and booting proceeds. Second, without the rhgb option in grub I can more clearly see what happens, I first reported "the screen will either go blank or graphic corruption will occur" but what is happening is a black screen, with the "X" mouse curson in the middle of the screen (unmoving) and some screen corruption (mainly in the lower portion of the screen). I should add these tests are still with kernel-xen-2.6.18-1.2693.fc6. OK: just so I'm understanding this right, it gets as far as trying to start X, regardless of whether we're using rhgb; and then it dies with a change_page_attr() bug in /var/log/messages? Definitely sounds like a dup of bug 207432 if that's the case. Regardless of rhgb it's failing at the same place, X. However _without_ the rhgb option I do not have anything untoward (change_page_attr) in my messages file. I'm going to run another few tests today : 1. Confirm GSI 21 boot problem. 2. Test with latest rawhide metacity. 3. Double check change_page_attr only happens with 'rhgb'. Confirmed, "GSI 21" lock up (can't even CTRL-ALT-DEL) happens with kernel-xen in both cold-boot, and warm-boot situations. This is a major blocker to my furtehr (X) testing. Latest rawhide makes no difference. Booting without 'rhgb' in my grub options removes the "change_page_attr" error message in my messages file but still I cannot boot, let alone into X. Also confirmed that kernel-xen 2699 fails to boot on my Dell Optiplex GX620, hanging at the "GSI 21" message. It requires a power cycle. Good news is the "change_page_attr" bug with gdm is gone under gdm-2.16.0-10.fc6. Problem confirmed under "2.6.18-1.2724.fc6 #1 SMP Sun Oct 1 19:43:37 EDT 2006 x86_64 x86_64 x86_64" as well. Just warm booted from kernel 2726 to kernel-xen 2741 and it booted up until such point as I had given my login details to GDM, at which point X locked, and a second later the machine was rebooting itself. There is nothing in the messages file to indicate what the error may be.. Oct 6 17:35:36 localhost kernel: ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 16 Oct 6 17:35:36 localhost kernel: [drm] Initialized i915 1.5.0 20060119 on minor 0 Oct 6 17:35:40 localhost gdm[2858]: no suitable security token driver could be found ..<here is pops it's cloggs>... Oct 6 17:37:31 localhost syslogd 1.4.1: restart. Oct 6 17:37:31 localhost kernel: klogd 1.4.1, log source = /proc/kmsg started. Oct 6 17:37:31 localhost kernel: Bootdata ok (command line is ro root=/dev/VolGroup00/LogVol00 rhgb quiet) Can you please try to capture the kernel boot output with serial console? It's really going to be impossible to debug this further without the kernel logs. Thanks. Understood, I don't have a second machine available so this will take some time. In the meantime though here are some notes. 2.6.18-1.2784.fc6xen - Does not boot, it prints "RedHat nash 5.1.19 Starting" and hangs until power cycle. 2.6.18-1.2759.fc6xen - Boots! Then dies on X. I did see on the console something akin to "BUG: spinlock (*big hex value here*) not tainted" And this was in my messages file : Oct 14 01:18:54 localhost kernel: [drm] Initialized i915 1.5.0 20060119

kernel: CR2: 000000000000005a I ran another test. I booted 2.6.18-1.2798.fc6xen into init 3 and ran a test of installing two DomU instances simultaneously and all worked a charm. So either somewhere along the line the "GSI" problem has been fixed, or I was randomly lucky. I'll close in case it was the former case. However, kernel-xen still fails to be stable when X is running on my system. I'll look at BZ 207883 & 207432. |
