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):

[SYSTEM HANGS HERE]
In other words, for 2.6.20 the discovery of the SCSI disks seems to
occur after mdadm has been started, and too late to be of any use -
lacking a root device, the system hangs.
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.
Best wishes,
Simon
