Description

Hi Bruno,

From a Backup mondoarchive of a Debian 8.2 system on a Dell T110 II server, when i boot with mondorescue iso, I can hit at the keyboard "expert", then when I get the shell prompt, my usb keyboard stops responding.

As it is mentioned in various old tickets, I try to add the missing modules (compared to mindi Version 2.1.7 revision 3184) in /usr/sbin/mindi file, USB_MODS variable, without success :

1/ ehci_hcd
2/ ehci_hcd usbcore
3/ ehci_hcd usbcore ehci_pci
4/ ehci_hcd usbcore ehci_pci libusual
5/ ehci_hcd usbcore ehci_pci libusual usb_common usb-common

On the same T110 II box, I can boot from a Debian 7 mondoarchive version 3.0.4 iso with no problem.

I can read at boot :

hidraw: raw HID events driver (C)Jiri Kosina
usbcore: registered new interface driver usbhid
usbhid: USB HID core driver

Restoring to a sytem without ps2 keyboard is no longer possible. Can you please help me ?

Clearly there is a missing module in your case (which probably changed due to diffs between the kernel of Debian 7 and the one of Debian 8).

Looking at your lsmod result, I'm questioning the utility of the following:

-------------
lsmod result:
-------------
Module                  Size  Used by
mpt3sas               148132  0 
dell_rbu               12727  0 

Also unsure of the ipmi even if I doubt they could play a role.

lpc_ich                20768  0 
mfd_core               12601  1 lpc_ich

You should probably also add mpt3sas, which I just added myself to mindi.

Let me know how it progresses. The real debug approach here is to try all the different drivers mentionned in lsmod between deb7 and deb8 and see which one is needed.

I did not find missing modules related to usb in debian 8. However I change to /usr/sbin/mindi this line : FORCE_MODS="mpt3sas dell_rbu mfd_core lpc_ich" and I try : no success.

Then I redo my tests with an HP Proliant ML350 G6 which has a ps2 port. With the mondobackup.iso for Debian 7 the usb keyboard work. With Debian 8 the usb keyboard does not work.

The presence of a ps2 keyboard allows me to retrieve mondorestore logs for debian 7 and 8. See attached files.

the result of lsmod in these two files shows no missing usb modules:

the result of dmesg in these two files shows USB keyboard is detected in Debian 7 and 8, but with no "input" and "generic-usb" line in Debian 8. That is the problem ?

The Debian 8 list has more drivers listed than Debian 7 and nothing missing. So contrzary to what I thought it may not be a module missing :-(

So maybe there is a daemon to launch in order to initiate the USB devices on Debian 8. Could you look at your process list to check that ?

Others usb devices like usb key or cdrom works on mondorescue shell system

But same keyboard,

connected to mondorescue shell system don't work:

I notice that, on mondorescue shell, the lsusb command does not work properly, and the directory /dev/bus/usb is missing. Is this may explain the keyboard problem ?

Now the question is : why /dev/bus/usb is missing when I boot with a mondorescue.iso backup of a debian 8 system ?

I notice this :

...
failed to insert 'hid_generic'
...

The "hid_generic" module is already in the USB_MODS variable of the /usr/sbin/mindi file. But, for that the usb keyboard works properly, we must also add the module "hid-generic".

Please can you add the "hid-generic" module in the /usr/sbin/mindi file ?
