Bug#843649: Unable to boot Jessie installed on usb drive on major of x86 archs computers
Source: linux
Severity: important
Hi, with Jessie amd64 I found a strange and important problem, Jessie
(persistent install, same as internal disk one) on usb drive don't boot
on major of pc(desktop), notebook and servers x86. From a fast search I
don't found solution or workaround for this.
I used Lenny, Squeeze and Wheezy for years on many different servers for
maintenance/install operations without problem but now with Jessie I'm
unable to boot on many servers, in particular the recent ones (4-5 years
old or less).
I did many tests, the first 1 year ago or more with debian 8.1 and
latest recently with 8.6, in both I used for install the netinst amd64
image taken from debian official site.
If I install it on pc/server where boot correctly install it successfull
but don't boot trying to boot on pc/servers where have the problem, it
arrive to busybox of initramfs and usb drive is not visible (with cat
/proc/partitions). If I try to install it on pc where don't boot do the
install except grub that "fails" without return error and fails to boot
also on pc where jessie can boot correctly.
I tried also kernel from backports up to 4.7 with same result.
I tried for test to install on usb drive ubuntu server (minimal) 16.04.1
and boot correctly also where Jessie fails. I tried 2 Jessie kernel
rebuild some CONFIG_USB... changes to make it similar to the ubuntu
kernel without solves the problem. I suppose there is something missed
or wrong about drivers needed/loaded.
I think this is an important problem even if I suppose debian install on
usb drive on x86 archs is not widely used.
Can someone solve this problem please?
Thanks for any reply and sorry for my bad english.
