My laptop running current rawhide hangs quite frequently at boot. I've got three screen shots of the hangs but I'm not sure how useful they'll be. It's the same hang but the screen output is different in each case. I tried to show all cases I've seen and the screen output is usually one of these three. The current 2.6.21-1.3125.fc7 kernel also doesn't power down at shutdown. This has been happening for the past 5 to 10 kernels or so (tough to estimate) but I didn't think of camera phone screen shots as a way of submitting a bug until now. I've included cpuinfo, lspci -vv, meminfo.

OK so it seems like it may have something to do with switching to high resolution mode with the CPUs?
Please test kernel 1.2932, which had a set of timer patches applied.
I've rebooted with the 3132 kernel five times and it's worked all five times so I think that it's fixed. I am still having a problem I half mentioned where if I log in to a full user session, possibly because of compiz, the system will then not shutdown or reboot. If I don't login, it seems to work fine but if I do, it hangs with the last message being "Power Down" on shutdown or "Restarting system" on restart. Should I open a different but for that?
Does the 3141 kernel have the changes from 3132 backed out? 3132 seems to boot consistently fine but the problems are back with the 3141 kernel. I also had some problems with 3141 - wireless stopped working, the keyboard stopped working, and I couldn't shutdown or reboot the laptop at all. I had to just push the power button. I really couldn't get any more information on what happened due to no network or keyboard.
I'm still getting this with the 3142 kernel as well. It will quite often take three times to successfully boot.
can you try to add the following three kernel command line option variants ? 1: highres=off nohz=off 2: highres=off 3: nohz=off Thanks, tglx
I'm experiencing a similar problem on my new D620 too. When using kernel 1.3104, it usually hangs at "Starting udev". I didn't have much issues with kernel 1.3149. It booted *most* of the time. Then when I started using kernel 1.3194, it hangs at "Uncompressing Linux... Ok, booting the kernel." all the time, unless I use nohz=off. Let me know how I can help to narrow down this problem.
Hello All Just too add my voice to the mix. I've just installed F7 RC2, and I've run in to this problem as well. booting with either of the following appended to the kernel gets my system up. highres=off nohz=off or nohz=off Booting with just highres=off results in a hang (almost identicle to the screen shots previously attached). Here is the hardware on the laptop http://smolt.fedoraproject.org/show?UUID=12df2cc3-ec44-4abf-a01e-c90e1ad9d1ad Let me know if any more info is required.
Please try build 3208 from http://people.redhat.com/davej/kernels/Fedora/fc7/
Dave, I tried build 3208. It did not boot with or without nohz=off. It appeared to be unresponsive when it's at "Uncompressing Linux... Ok, booting the kernel." Eugene

When I was using build 3194 just now, a warning and backtrace appeared on the console. Not sure if it is related to this bug but please see the attached screenshot (comment #15). Thanks.
I'm still seeing the hang after switching to high resolution mode with the 3208 kernel. Often takes four or five boots to get past it but it does work sometimes.
Another observation: with the power plugged in, my laptop hung after the high resolution mode was set 8 times in a row. I unplugged it and it booted the first time. I know it has hung before when unplugged but it seems to hang more plugged in.
Just installed F7 from DVD and unfortunately, the only way I could get my laptop to boot was with highres=off nohz=off on the command line. Due to this bug being intermittent and me wanting to have iwlwifi work, I believe I didn't test the 3194 kernel very long, if at all. I think a 3197 one was out via koji or Dave's repo before I ever got 3194 installed (due to slow syncing of my mirror). I hope this bug doesn't bite too many people. Now off to find the bug about lvm root labeling not working correctly. As soon as I got past this bug, my laptop still wouldn't boot because it couldn't find root.
I am now running with kernel-2.6.21-1.3228.fc7, I no longer nead either nohz=off or highres=off the system boots as I would expect with out any additional parameter. I would assume this bug can now be closed.
I still get hangs with the 3228 kernel. I don't seem to be able to boot at all with the power plugged in. It boots relatively reliably on battery but if it's on the charger, it's <10% success. Dell Inspiron XPS M1210 with A07 BIOS.
The 2.6.22 kernels seem to have fixed this for me. I haven't had any problems booting on or off the charger. I've had some other bumps with the 6.2.22 kernels (iwlwifi, usb) but it seems that the -33 version fixes everything. I won't close this as others may still be having the problem but I'm good. Thanks!
