Package: linux-image-2.6.20-1-686 Version: 2.6.20-3 Severity: critical Justification: breaks the whole system
Hi, I've filed this bug under the this package since, although one could argue that initramfs-tools has the problem, the difference appears to be kernel version. My machine is configured with an software raid 0 (mdadm) root filesystem, composed of two SCSI drives. If I run the stock debian etch linux-image-2.6.18-4-686 (2.6.18.dfsg.1-12etch1) kernel, everything works as expected. If I attempt to boot the linux-image-2.6.20-1-686 (2.6.20-3) kernel from unstable, my system hangs on boot. Examining captures of the boot process shows that on 2.6.18-4-686 we see (excuse slight hiccups in formatting - imperfect capture from serial over LAN console): Begin: Running /scripts/init-premount ...

My suspicion is that adding a suitable sleep into the initrd scripts will "fix" the problem, but this doesn't seem like the right thing to do. As far as I am aware I have no exceptionally long delays in device discovery on the machine, and everything works swimmingly with earlier kernels.
