But installer and LiveCD using the same kernel works. Upgrading kernel to latest do not work. Booting stops while detecting lvm volumes. Host OS is Ubuntu, kernel 2.6.20-16-generic, kvm 16-1ubuntu2, Core Duo T2500. Command line: kvm -m 384 -hda fedora-devel.i386.qcow2 Version-Release number of selected component (if applicable): 2.6.21-1.3228.fc7 How reproducible: Always Steps to Reproduce: 1. Install F7 using KVM. 2. Boot installed F7 Actual Results: Booting halted with soft lockup. Expected Results: Booting should suceed. Additional info: See attached screenshot.
Created attachment 159737 [details] Screenshot of failed boot. There are two screenshots here. First is normal boot. Second is after replacing "quiet" with "verbose" in kernel command line ine GRUB.
This is fixed in 2.6.23-rc1. A backport of the patches to older kernels is possible.
Still happens with 2.6.22.4-65.fc7.

Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems after applying the patches Avi mentioned? You can also test with a development kernel or 2.6.23 which should be released shortly. If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged. Cheers Chris
I don't see 2.6.23 for fc7 at davej's webpage right now. I will wait till this kernel appears.
> I don't see 2.6.23 for fc7 at davej's webpage right now. I will wait till > this kernel appears. The patch from comment #5 is in kernel 2.6.22.5 and above, no need for 2.6.23. Did you test any releases after 2.6.22.4-65?
I think that for this a new userspace is required, not a new kernel. Or maybe both.
Sorry, someone removed me from CC and I didn't get any comments for a while. Anyway, kernel 2.6.22-9.91.fc7 halts same way. No improvement. Avi, what new userspace do you mean? Newer version of kvm/qemu in Ubuntu (host os)?
I just installed F7 32-bit from the DVD and booted it, using kvm-46+. I suggest trying the latest snapshot from http://people.qumranet.com/avi/snapshots/. Most likely using it's the new userspace (including the bios) that's needed. If not, we can try and find exactly what fix is needed for the kernel and backport it.
Responding more clearly to the question in #11, yes, a new version of qemu with the kvm patches.
Thanks for all your input. I've just installed kernel 2.6.23.fc7 from updates-testing and it boots on KVM. So this issue is fixed.
