Hi, I noticed a regression report on Bugzilla ([1]). As many developers don't have a look on it, I decided to forward it by email. See the report for the full thread. Quoting from the report: > Azamat S. Kalimoulline 2021-04-06 15:45:08 UTC > > Same as in https://bugzilla.kernel.org/show_bug.cgi?id=212133, but not StoneyRidge related. I have same issue in 5.11.9 kernel, but on Renoir architecture. I have AMD Ryzen 5 PRO 4650U with Radeon Graphics. Same stuck on loading initial ramdisk. modprobe.blacklist=amdgpu 3` didn't help to boot. Same stuck. Also iommu=off and acpi=off too. 5.10.26 boots fine. I boot via efi and I have no option boot without it. Azamat, can you try reproducing this issue on latest mainline? Anyway, let me add this regression to regzbot: #regzbot introduced: v5.10..v5.11 https://bugzilla.kernel.org/show_bug.cgi?id=212579 #regzbot title: Booting kernel on AMD Ryzen 5 PRO stucks in loading initrd Thanks.
