Description of problem: Sometimes boot hangs very early after grub Even before it asks for encryption key for the disk. Once up, it is running perfectly with Xfce Suspend-resume perfectly including wifi. Resuming from hibernation: same occasional problem as normal boot. But as it is just to try again until it boots, and resuming works so i do not set this bug critical because user do not loose work. System: Laptop Dell Precision M4400 (bought used recently) CPU: Intel Core 2 Quad Q9100 (fam 6 mod 23 step 10 Cpuid 13) 2,26MHz 4GB RAM GPU: Nvidia G96GLM (Quadro FX 770M) Driver: nvidia Geforce 8100 to 415 Disk: SSD, separate /boot, then rest of system in LVM lv:s in a LUKS encrypted pv. How reproducible: § About every third try in general, but may file twice in a row, or work several times. § Reboot or cold start does not seem to matter § MSWindows10 is installed in dual boot configuration and have no problem (but i have only booted less than ten times) § Once Mageia is booted, never any problems during ten hours use total this far. § Update to later kernels. Possibly 5.5 series works a tiny bit better, hard to judge. § If i in BIOS settings enable virtualisation, it always fail § If i disable speedstep it seem to work a bit better § No BIOS setting seem to get rid of the problem, i have tried to disable serial parallel esata and other ports and hardware. Steps to Reproduce: 1. Install Mageia 7.1 ( I used LVM and encryption but as it dont get that far in but i dont think that matters ) 2. Boot. In Grub edit kernel boot line parameters: remove splash quiet so you see what happens. If you are lucky it works. Else retry until it does. It reboots from Ctrl-backspace-backspace. Grub kernel line: linux16 /vmlinuz-5.5.9-desktop-1.mga7 root=/dev/mapper/vg--mga-lv_root ro noiswmd nokmsboot resume=/dev/vg-mga/lv_swap audit=0 vga=797
All previous tests were with -desktop kernel flavour. Now i have tried kernel-linus-5.4.20-1.mga7 It failed four times in a row. Fifth time it passed so long i entered luks key. I had selected maintenance mode so there i pressed Ctrl-D and it booted a tiny bit further until it hung hard. Had to press power button. On trying again now, grub is destroyed, i only get grub > Hrmf.

Created attachment 11548 [details] Picture of screen at boot failure Here is a picture i took of the laptop screen two days ago i think. Kernel 5.5.6 if i recall correctly. Boot seem to progress fine for two seconds, then noting happens for almost 6 seconds when the line "random: crng init done" get written. Then there is almost a minute until it writes out stall is detected. If i keep waiting it repeats that messages (call trace etc) about every minute.
Still valid kernels 5.5.14 and 5.5.15. 5.5.15 also have problem suspending in this machine, Bug 26440.
For lspci output see that bug
Not a sign of problem on Mageia 8 Lives nor installed. Same machine. Also no one else reported problem, so I assume problem is gone on mga7. Hibernation and resuming is an issue i will later look at...
