Can you confirm whether CFS is involved, i.e. does it spin like that even without the CFS patch applied?

I will try that, but not until Tuesday night. I've been here too long today and have an out-of-state meeting tomorrow. I'll take a look after dinner. Note that the latest 2.6.21 with cfs-v19 doesn't have any problems of any nature, other than suspend to RAM not working, and I may have the config wrong. Runs really well otherwise, but I'll test drive 2.6.22 w/o the patch.

hmmm .... could you take out the kernel/time.c (sys_time()) changes from the CFS patch, does that solve the automount issue? If yes, could someone take a look at automount and check whether it makes use of time(2) and whether it combines it with finer grained time sources?

Will do.
