Subject: Nvidia related kernel panic on boot, *unless* the keyboard is tapped
So here is an odd one
Ever since the upgrade to 7.3, when using the el-repo kmod-nvidia, boot
hangs around the 'mounted /boot' point. If left it then kernel panics
However at that point, tapping the keyboard gets it going again. As I'm
using a wireless keyboard, even the act of switching the keyboard on
gets it going again
This doesn't happen without the kmod, and I'm in the process of
capturing the panic to file the bug report with el-repo, but for the
sake of conversation has anyone seen anything like this before, or have
any idea why that could happen?
cheers
Dunc
I have not checked to see if elrepo has kicked out all the new drivers to fix it since then, but apparently RH changed some kernel 'pointers' in 7.3 which kind of messes up some of the kmods:
https://elrepo.org/bugs/view.php?id=715
https://elrepo.org/bugs/view.php?id=710
I am betting that you installed the kmod-nvidia before the upgrade to 7.3 and thus did not get the kind of warning that those folks did.
Perhaps even related to this issue:
https://elrepo.org/bugs/view.php?id=693
which kmod-nvidia do you have? At the bottom of 693, pperry indicates: "kmod-nvidia-367.57-2.el7.elrepo.x86_64 is for EL7.3".
The most recent, I did obviously get the brief error where the centos
kernel release hadn't quite caught up, but that was a while ago.
Once booted the driver itself works perfectly, Its just so odd I get the
kernel panic unless I tap the keyboard during boot
