[gentoo-user] udev and external harddisk, some more info

[Willie Wong <wwong@Princeton.EDU>]

(This is not a duplicate of the mail I sent yesterday, though,
curiously I never got that one back from the list [It did make gmane])

To recap: when I plugged in my harddrive, the kernel recognized the
device, but udev failed to create the appropriate entries in /dev. 

I know that udev did receive the events, because udevmonitor shows so
and because the appropriate device appeared under /sys/block/sda (and
other places it is supposed to go).

One curious thing though: because I remembered that usb-drives used to
work about a year ago with my mp3-player, I tried downgrading udev,
and it works!

So somewhere between udev-068-r1 and udev-087-r1 something changed so
that the device nodes are not created. 

I am running the 2.6.11-hardened-r15 kernel. 

(I am assuming that using a usb mass storage device is a common enough
thing that, the fact that I don't see anything on bugzilla about this
means something is misconfigured on my end.)

Any ideas?

`Yeah,' said Zaphod, `but don't shout it out or they'll all 
want one.'
`THE Zaphod Beeblebrox?'
`No, just A Zaphod Bebblebrox, didn't you hear I come in 
six packs?'
`But sir,' it squealed, `I just heard on the sub-ether 
radio report. It said you were dead...'
`Yeah, that's right, I just haven't stopped moving yet.'"
