swapon -a freezes after post-crash reboot

Description of problem:
I'm not sure swapon is to blame, but every time I reboot any of my boxes after a hang, swapon hangs as well. Sometimes it's not a complete system freeze, since I can switch to VT1, issue SysRq commands and get another reboot (otherwise it just sits there, unresponsive to network and all, since swapon is pretty early in the boot). At other times, it freezes hard, and not even the mouse or caps lock work on rhgb.
Version-Release number of selected component (if applicable):
FC5T1, FC5T2 and IIRC FC4 as well
Steps to Reproduce:
1.Manage to crash the system such that you have to power-cycle it (not sure the crash is necessary, come to think of it, maybe just a power-cycle would do)
2.Boot it back up
3.Watch as rhgb says it's starting swap
4.Wait for the next line
Actual Results: Nothing happens. Sometimes it freezes hard again, sometimes you can perform a nicer reboot. Either way, you have to be at the console to fix it.
Expected Results: Unassisted reboots, especially after power failures or so, should be supported.
I haven't had this problem lately, even though I've had lots of system freezes
because of various problems, so it looks like the problem is fixed.
Thanks for your feedback!
