Okay - I’ve tried a series of combinations for the Qubes 4.1.2-rc1 image - some result in the machine:
Just rebooting
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0
Kernel -= quiet
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0
Kernel -= quiet
Kernel += module_blacklist=amdgpu
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0
Kernel -= quiet
Kernel += nomodeset
``
Failing to reach the installer
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0
Kernel -= quiet
Kernel += acpi=off module_blacklist=amdgpu
=> kernel running -- with errors like:
xhci_hcd "Can't find IRQ for PCI INT .."
nvme nvme0: I/O QID 0 timeout, completion polled
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0 acpi=off
Kernel -= quiet
XEN += dom0_max_vcpus=1 dom0_vcpus_pin=1 acpi=off
Kernel -= quiet
=> Hang with
"usb usb6. We don't know the algorithm for LMM for thsi host, disabling LMM"
Starts the installer - but with at 'sloppy' screen/mouse
XEN += dom0_max_vcpus=1 dom0_vcpus_pin=1 acpi=off
Kernel -= quiet
Kernel += module_blacklist=amdgpu
XEN += dom0_max_vcpus=1 dom0_vcpus_pin=1 acpi=off
Kernel -= quiet
Kernel += nomodeset
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0 acpi=off
Kernel -= quiet
Kernel += nomodeset
I repeated some of the tests with the 6.1.7 kernel - the “best” result were with:
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0 acpi=off
Kernel -= quiet
Kernel += nomodeset
where the installer starts but tells me that my machine is “Unsupported Hardware”, without IOMMU/VT-d/AMD-Vi (after I accept running a release candidate) - and
XEN += clocksource=tsc tsc=unstable hpetbroadcast=0
Kernel -= quiet
Kernel += acpi=off
ends with “Wait for Complete Device Initialization” and “nvme nvme0: I/O QID 0 timeout, completion polled” (before the installer starts).
Finally testing with
XEN += clocksource=dom0_max_cpus=1 dom0_vcpus_pin=1
Kernel -= quiet
Kernel += acpi=off
I get to the point where I can select installation destination and actually install the system. This looks the same as the images I’ve tested from mirror.netset.fr.
I suspect something with ACPI - but any hints/suggestions to what to try next are welcome – I keep an eye on the Lenovo site, to see if/when a new BIOS should show up.
