 Posted: Sat Jan 18, 2025 8:11 am Post subject: DMESG: silent gap in boot process |
 |
|
I have upgraded my cpu from Ryzen 7 200 (8 cores) to Ryzen 9 5090X (16 cores).
On the old cpu, there was a 20 second 'silent' gap in the boot process. With the new cpu the gap has grown to around 50 seconds.
The relevant part of dmesg output is below. I can see that the initramfs has not started in this gap - since it appears in dmesg output further on.
It's not a problem, since the machine is not booted often. This post is really just to see if someone can help me understand what is happening in the silent gap.
