From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-2 Firefox/1.0.3 Description of problem: After updating yesterday to the 1251 kernel, my Dell Inspiron 600m with just a standard ide disk crashed on boot after not finding/activating any lvm partitions in the single lvm on this system. Because the meat of the error scrolled off the screen, I rebooted and added vga=792 to the kernel cmdline so I could see what was happening. Sad thing is, it booted fine. This afternoon, I updated to the 1253 kernel and am experiencing the same thing. Before the kernel panic lines, it says something to the effect of "/bin/lvm exitted with an error". It sees the lvm because it prints something about vgc0 but it can't see the partitions in it. By adding vga=792, the error doesn't occur. Maybe it's a timing thing and the higher resolution slows something down just enough? Version-Release number of selected component (if applicable): kernel-2.6.11-1.1251_FC4, kernel-2.6.11-1.1253_FC4 How reproducible: Always Steps to Reproduce: 1.boot the 1251 or 1253 kernels on his 600m laptop 2. 3. Actual Results: kernel panic after not being able to activate any partitions in lvm vgc0 Expected Results: partitions are seen and boot occurs normally. Additional info: I'll reboot one more time to give the exact lvm error.
It actually is not finding any volumes. I get the error "No Volume Groups Found" and then ERROR: /bin/lvm exited abnormally! The vgc0 must be being picked up from the kernel cmdline. These kernels works fine on another test system I have but that one is SCSI based.
I just had it happen even with the vga=792 so that's not a perfect fix. Since I did have it enabled, I was able to see pretty far back in the boot sequence. There were two instances of "/bin/udevstart exited abnormally!" so that might have had something to do with it. When this happens, the three finger salute doesn't work and I have to power cycle the machine so it's not due to hardware being left in some funky state. It happens from a cold boot. If it matters, I also have had consistent problems with FC4Tx kernels and resume not working reliably and also with cpuspeed not working all the time. I'll file a separate bug about cpuspeed.
FWIW, the cpuspeed problem seems to be bug #137995.
I'm still seeing this with the 1261 kernel. It's now happening on two laptops, a Dell 600m and a Dell 7500. It sometimes takes three or four boots before the lvm partitions are seen correctly.
This seems to be fixed in later kernels.
