wie man sieht, habe ich in der fraglichen session, in der ich das system gefetzt haben muss, extrem viel software installiert, unter anderem auch einen neuen kernel ( 2.6.31.3 -> 2.6.31.4 ) (das kernelupdate war auch der anlass für den neustart)
Ich habe bereits versucht, den kernel auf die alte version zu downgraden; dies hat das problem nicht beseitigt.

In #archlinux konnte/wollte mir niemand helfen.


In der Hoffnung auf Hilfe,

EDIT:
Ein USB-Stick am gleichen/anderen Anschlüssen funktioniert einwandfrei.

EDIT 3:
slackfan hat sich mein pacman.log durchgelesen und ihm ist diese stelle ins auge gesprungen:

[2009-10-13 15:26] installed sg3_utils (1.27-2)
[2009-10-13 15:26] installed libatasmart (0.14-1)
[2009-10-13 15:26] installed devicekit-disks (007-1)
[2009-10-13 15:26] installed gnome-disk-utility (2.28.0-1)
[2009-10-13 15:26] upgraded gvfs (1.2.3-1 -> 1.4.0-1)

daraufhin habe ich eine alte version von gvfs eingespielt, gnome-disk-utility und devicekit-disks deinstalliert, und schon war das problem gelöst. toll, nä?

Also: devicekit-disks war schuld, all glory to slackfan.
