TL;DR if you have a working rawhide system, you may want to refrain from updating it for a little while. I have been maintaining a headless rawhide system for more than two years, updating every 1-4 days. There have been a few hassles, but nothing terrible. Today however, after an update and a yum-complete-transaction (which killed all connections), it became unbootable. It could be my fault for not waiting long enough before power cycling it -- in case the complete-transaction was still running. I tried the preceding kernel with the same result. I haven't given up, but was motivated to get a working rawhide system: I'm releasing coreutils-8.10 tomorrow and the only btrfs that was new enough to pass a failing test was on rawhide, yet there was one other test that failed even on rawhide, and Josef Bacik had given me a hint on how to work around it (use filefrag's -s option). Thinking it might be easier to install a new system, I first tried the latest nightly, desktop-x86_64-20110130.16.iso, but that has its own problem: "Install to harddrive" fails with "not a live image" http://bugzilla.redhat.com/672265 So I installed from an F14 image, updated, then tried to upgrade to rawhide. There were lots of package conflicts and my VM was oom-killed, so I had to rebuild the rpm db (so again could be my fault), but in the end, with the new kernel, the system fails to boot, now with this: [ 0.021998] NMI watchdog disabled for cpu0: unable to create perf event: -2 [ 0.035026] NMI watchdog disabled for cpu1: unable to create perf event: -2 [ 0.047172] NMI watchdog disabled for cpu2: unable to create perf event: -2 [ 0.059012] NMI watchdog disabled for cpu3: unable to create perf event: -2 [ 0.737139] Kernel panic - not syncing: UFS: Unable to mount root fs on unXno wn-block(0,0) [ 0.737820] Pid: 1, comm: swapper Not tainted 2.6.38-0.rc3.git0.1.fc15.x86_64 #1 [ 0.738435] CaII Trace: [ 0.738714] [<ffffffff814673e7_] T panic+0x91/0x19c [ 0.739252] [<ffffffff81b58211_] T mount_block_root+0x250/0x27b [ 0.739809] [<ffffffff81b583c2_] T mount_root+0x53/0x57 [ 0.740284] [<ffffffff81b58533_] T prepare_namespace+0x16d/0x1a6 [ 0.740808] [<ffffffff81074387_] T put_cred_rcu+0x0/0x8f [ 0.741283] [<ffffffff81b57efd_] T kernel_init+0x29d/0x2a2 [ 0.741651] [<ffffffff8100a9e4_] T kernel_thread_heIper+0x4/0x10 [ 0.741883] [<ffffffff81b57c60_] T kernel_init+0x0/0x2a2 [ 0.742109] [<ffffffff8100a9e0_] T kernel_thread_heIper+0x0/0x10 Next time I'll save a copy of the updated F14 system before jumping into rawhide. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
