The processing uevents settle timeout takes ~3 minutes of wallclock time right now. The timeout value seems to be totally ignored, or it's re-running the timeout too many times.
The init-script just calls udevadm settle --timeout=${udev_settle_timeout:-60} and that has not changed since, so should not be responsible for wrong timeouts. The only settle related changes in udev-git I can find are these patches commited right before version 140: bb38678e3ccc02bcd970ccde3d8166a40edf92d3 udevadm: settle - synchronise with the udev daemon c2c24d4d3c8f83c5f4507bb13ba6c989f9d6ea45 udevadm: settle - use timeout signal, instead of loop counter So you could bisect the binaries via bisect make make install or emerge selected versions via EGIT_TREE="..." emerge =udev-9999
I did a two-part change: 1. hardcode timeout argument to 15. 2. change the DEFAULT_TIMEOUT define to 25 (from 180) recompiled, rebooted, no change in the actual result. I'm wondering if it might be related to the 2.6.30-rc kernels.

Maybe you want to enable a parallel running udevmonitor and watch its log and timestamps. Or use bootchart to see what processes are running in parallel.

This seems fixed in 197-r2 which is going stable. See prev. comment.
