Installed packages: kernel.x86_6 2.6.38.2-9.fc15 systemd.x86_64 21-2.fc15 systemd-units.x86_64 21-2.fc15 Boot with "systemd.log_level=debug systemd.log_target=kmsg rd_NO_PLYMOUTH", remove the "rhgb quiet" params. Then reproduce the failure to reboot and let us know what is displayed on the screen when it hangs. Use a digital camera perhaps. Created attachment 489365 [details]

No problem
Unfortunately I can't monitor the serial console on this box. I think I am missing some logging after the screen blanks.
Also, if I initiate shutdown the PC shuts down correctly, however on reboot it enters the same loop where the system can be heard ticking over. Does you system reboot if you run "reboot -f"? And how about "systemctl --force reboot"? Hmm, so this seems to freeze somewhere after systemd execs /lib/systemd/systemd-shutdown replacing PID1. That tool kills all remaining processes, detaches all file systems, dm devices, loopback devices, swaps. I wonder if something of that causes the freeze. Do you use LVM, or have any other non-traditional storage setup? Nothing unusual here, 8 partitions over two drives - I have an F14 install on another partition which reboots OK. In reply to comment 7: will try this later - is remote to me at the moment.

Reassigning to kernel. Please attach the output of "lspci -vvvnn" and "dmesg". Perhaps it will provide a clue. Does changing the kernel reboot options help? reboot=b[ios] | s[mp] | t[riple] | k[bd] | e[fi] [, [w]arm | [c]old] | p[ci] warm Don't set the cold reboot flag cold Set the cold reboot flag bios Reboot by jumping through the BIOS (only for X86_32) smp Reboot by executing reset on BSP or other CPU (only for X86_32) triple Force a triple fault (init) kbd Use the keyboard controller. cold reset (default) acpi Use the RESET_REG in the FADT efi Use efi reset_system runtime service pci Use the so-called "PCI reset register", CF9 force Avoid anything that could hang. I would try "reboot=a" or "reboot=t" first. Thanks for the reply - so far I've tried a/t/p/ with the same result. As mentioned before, if I power off then power on at a alter time, the system does not reboot but needs to be manually reset. Will try e/w/c/k next This problem disappeared for me with 2.6.38.3-18 |
