weird kernel issue [Solved]

#1 Post by anticapitalista » Thu May 31, 2018 10:08 am

On my Thinkpad L412, all new antiX kernels post 4.9.91 (32 and 64 bit) boot with an xorg delay of 20-30 seconds.
If I tap the keys of the keyboard or move the mouse, it boots to desktop 'normally' with no delay.

The kernel .config is identical. The hardware is identical as are all the apps.
It happens on installed to hard drive, frugal and installed to VBox.
Corrected - Running live-usb with/without persistence seems to work ok.

Anyone got any ideas why and how to fix? Obviously something has changed in the upstream kernel.

Does dmesg give you a clue where it gets stuck?

No. dmesg shows the boot before Xorg kicks in. This part of the boot is ok. Xorg shows a delay. Here is the end of xorg.log

FYI: mx "test" repo is not the same thing as debian testing repo.

Seems to be, yes.
The desktop doesn't show this issue.

the mouse movement clue suggests the delay is related to "entropy generation" -- building a random set of data for use in GPG encryption, SSL certs, etc
