Bug#615831: [PATCH] Load modules for USB keyboard if not keyboard is present at panic
USB modules are not normally loaded at break=top time but since USB keyboards are very common we should take the effort to try to load extra kernel modules at break (=panic) time. This patch closes #615831 and has been adapted from comments mentioned in https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/229732 and tested on on HP ProLiant MicroServer that lacks a PS2 port completely. --- scripts/functions |7 +++ 1 files changed, 7 insertions(+), 0 deletions(-) diff --git a/scripts/functions b/scripts/functions index 579696a..778196f 100644 --- a/scripts/functions +++ b/scripts/functions @@ -46,6 +46,13 @@ panic() fi modprobe i8042 modprobe atkbd + if ! grep -q '^H:.*kbd' /proc/bus/input/devices ; then + # no keyboard?

I have never seen a system where the BIOS does not provide a working USB keyboard, but I have no objections in principle. My only request is that the loading in panic() of *every* module is preceded by printing on the console an appropriate debug message containing the module name, because loading the module could cause an oops. -- ciao, Marco signature.asc Description: Digital signature
