R5500 G6 intel install ubuntu22.04.4 select install then black screen freezes

A customer site uses R5500 G6 Intel+P800 with Ubuntu 22.04.4 installed. Attempts to mount the image via HDM or install via USB all result in freezing at a black screen after selecting install. After switching to Ubuntu 22.04.2, an error occurs and the system freezes upon selecting install: efi stub: loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path. Discharge static electricity test was ineffective.

1. Reserve P800, remove other PCIE device for testing, issue persists.

2. On the install page, press the e key to edit GRUB boot option, locate the line starting with linux, add parameter at the end: acpi=off, issue resolved.

To address the issue of installation interface freezing, consider adjusting boot parameters in GRUB by disabling ACPI (acpi=off), disabling graphics drivers (nomodeset or nouveau.modeset=0 for NV/AMD GPUs), or disabling IOMMU (iommu=soft). Combinations can be attempted. Example:linux /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed quiet splash acpi=off nomodeset
