Ubuntu 18.04 无法在没有 nomodeset 的情况下启动，最后一条消息是“从 efi vga 切换到 inteldrmfb”

在发生过热事故或不幸的更新后，我的 Ubuntu 18.04 安装仅使用nomodeset内核参数启动。这不行，因为radeon驱动程序不想使用nomodeset：

$ sudo modprobe -f radeon 
modprobe: ERROR: could not insert 'radeon': Exec format error
$ dmesg |tail -2          
[  168.641843] [drm] VGACON disable radeon kernel modesetting.
[  168.641865] [drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!

如果我不启用nomodeset，启动过程会在switching to inteldrmfb from efi vga出现消息后冻结。我真的很想在没有 的情况下正常启动我的系统nomodeset。

我使用的是linux-generic-hwe-18.04内核。之前启动成功但现在失败的是Linux version 5.4.0-90-generic (buildd@lcy01-amd64-026) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #101~18.04.1-Ubuntu SMP Fri Oct 22 09:25:04 UTC 2021 (Ubuntu 5.4.0-90.101~18.04.1-generic 5.4.148)

我尝试了几种不同的内核https://kernel.ubuntu.com/~kernel-ppa/mainline/(5.4.189, 5.4.70) 但这没有帮助：启动在同一点冻结。我还尝试了在这种情况下建议的其他内核参数：amdgpu.dc=0但这intel_iommu=on没有帮助。

也许除了内核之外还有其他因素导致启动中断？

答案1

使用module_blacklist=radeon内核参数启动没有任何问题，我甚至能够使用双显示器，我担心我再也无法使用了。我猜我的 Radeon 卡不再起作用了，当驱动程序尝试启用它时，系统会冻结。
