and then a little later, another oops while loading dcdbas:

Hardware is a Dell E4300, BIOS A05, with a docking station (that
includes parport) attached.  I don't see the parport oops when booted
without the docking station, but the dcdbas oops is still present.

I've attached the complete dmesg; more debug info is available at
http://web.hexapodia.org/~adi/sysinfo/1242072617_cvpe4300_2.6.30-rc5-dmar-00096-ga4d7749/
