I have only minor stuff to add. First, it also affects IBM Thinkpads T2x with UltraDock II Stations (Type 2631). I have a half-baked workaround. Set PCI IRQ handling in the BIOS to AUTO (that's not the default for T2xs.) Pass the ACPI=force and irqpoll (optional, i found it working with and without, but without irqpoll the sound will fail occasionally) argument to the kernel. Now a 2.6.15 kernel will always assign the primary HD to hde. Ugly, but realiable. Oh, you loose USB connectivity this way.
Second, the bug propagated to Debian Etch and probably SID. -- udev enumeration should use /sys/bus not /sys/devices https://launchpad.net/bugs/6367 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
