Bug Description
Binary package hint: initramfs-tools
(I suspect there's a kernel bug at heart here, feel free to reassign as necessary)
After upgrading a hardy install to intrepid alphas (starting with kernel 2.6.27-4, and also -6, and now -7), I've had problems booting which I've narrowed down as in the subject.
The problem manifests itself in the initrd, as the system hangs at multiple seemingly unrelated points (eg, waiting for root filesystem, setting the keymap, etc. I'll attach a few dmesg logs, for timestamp comparisons), although it's only a "soft" hang. If I press any keys it'll break out. (While debugging this, I got in the habit of just holding down a Control or Shift key)
With the addition of the ACPI module "ac" to /etc/initramfs-
