Manjaro doesnt boot everytime

Hello all,

I got a new Dell Latitude 5500 laptop, and i have a pretty weird issue I never had before.
When I boot my Manjaro leaving all at defaults (Kernel 5.8), sometimes I get stuck a black screen, sometimes i get stuck on the Dell logo, and sometimes it boots just fine ( but unfortunately, most of the time it’s stuck ).

The only way I found to get it booting everytime is by using the initramfs-fallback entries in grub.
I have 3 Kernel installed 5.4, 5.7 and 5.8. Same issue for each, and any initramfs will work at first try.
Note that i have a nvme and it is full LUKS’ed

I did inspect journalctl -b but the only suspicious logs I found are those ones:

Oct 15 10:13:48 L5500 kernel: usb 1-3: device descriptor read/all, error -71
Oct 15 10:13:49 L5500 kernel: EXT4-fs error (device dm-0): ext4_validate_inode_bitmap:100: comm postgres: Corrupt inode bitmap - block_group = 1345, inode_bitmap = 44040209
Oct 15 10:13:57 L5500 lightdm[1091]: gkr-pam: unable to locate daemon control file
Oct 15 10:16:13 L5500 pulseaudio[1551]: ALSA woke us up to write new data to the device, but there was actually nothing to write.
Oct 15 10:16:13 L5500 pulseaudio[1551]: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers.
Oct 15 10:16:13 L5500 pulseaudio[1551]: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

Honestly, I have no idea of what could be wrong, maybe LightDM failing to load ? Then why initramfs works ?

After further investigation, it seems it was a BIOS issue and a bios update fixed it:

I went from 1.6.3 to 1.9.1

sudo fwupdmgr refresh
sudo fwupdmgr get-updates
sudo fwupdmgr update
