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

Message-Id: 20060817184630.GA9887@princeton.edu
1 (This is not a duplicate of the mail I sent yesterday, though,
2 curiously I never got that one back from the list [It did make gmane])
3
4 To recap: when I plugged in my harddrive, the kernel recognized the
5 device, but udev failed to create the appropriate entries in /dev.
6
7 I know that udev did receive the events, because udevmonitor shows so
8 and because the appropriate device appeared under /sys/block/sda (and
9 other places it is supposed to go).
10
11 One curious thing though: because I remembered that usb-drives used to
12 work about a year ago with my mp3-player, I tried downgrading udev,
13 and it works!
14
15 So somewhere between udev-068-r1 and udev-087-r1 something changed so
16 that the device nodes are not created.
17
18 I am running the 2.6.11-hardened-r15 kernel.
19
20 (I am assuming that using a usb mass storage device is a common enough
21 thing that, the fact that I don't see anything on bugzilla about this
22 means something is misconfigured on my end.)
23
24 Any ideas?

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