I try to come up with something, but I'm travelling tomorrow, so it

Thanks, Thomas.

I believe we definitely want to nail this down before 2.6.22-final,
but there's a good workaround in the interim (CONFIG_DETECT_SOFTLOCKUP=y)
and we've got at least a couple of months 'till then.

I think I may have fiddled with the RTC config, so I'll compare with my
old config and see what changed.

Okay.  I turned on CONFIG_COMPAT_VDSO=y and now the system fails to start up
in the same way/place as before.

Rebuilding again with CONFIG_COMPAT_VDSO not set, and all is as "well" as
before -- system starts up so long as CONFIG_DETECT_SOFTLOCKUP=y is given.

Cheers
