So many will now the Thinkpad E485 with Linux is a mess, because of the bad BIOS from Lenovo.
No I got it working with some kerne parameters for the last years. I have updated my kernel yesterday and now my arch can't boot.
BIOS version 1.27
Those are my kernel parameters:
amd_iommu=off ivrs_ioapic[32]=00:14.0 idle=nowait
I tried the kernel parameters from the wiki page as well: https://wiki.archlinux.org/title/Laptop … nkPad_E485
I have tried to boot from a freshly created USB stick as well (it boots flawless on a P53)
Here is a output with loglevel=7 (can't get hold of it any other way i guess)

Now one line that catched my eye was around timestamp 2.33
ccp: 0000:05:00.2: enabling device (0000 -> 0002)
ccp: 0000:05:00.2: ccp enabled
ccp: 0000:05:00.2: psp: unable to access the device: you might be running a broken BIOS.
but im not sure it actually is the cause.
UPDATE 25.08: I flashed my BIOS with the most recent version 1.61. Issue remains
OK is created an USB Boot Stick with the 07-01 release. and it booted withouth issues. To revalidate it is the new kernels version (5.18.16) I recreated the usb boot stick with the current release. It boots from usb stick. Seems more like my configuration is broken
Last Update: I worked all day on that issue. But finally I have it working again. I DO NOT NEED ANY KERNEL PARAMETERS. I had issues with grub afterwards, but i just completely reformatted bei GPT/EFI Partition and generated grubcfg and fstab new. Works like a charm.
Can be closed.
