Hi, After v4.14, I've been unable to boot my AMD compilation box with the v4.15-rc mainline Linux. It just ends up in a silent reboot loop.
I bisected this to: commit fa564ad9636651fd11ec2c79c48dee844066f73a Author: Christian König <[email protected]> Date: Tue Oct 24 14:40:29 2017 -0500 x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f, 60-7f) System details: [ 0.000000] DMI: MSI MS-7699/760GA-P43(FX) (MS-7699) , BIOS V1.3 10/14/2014 [...] [ 0.070000] smpboot: CPU0: AMD FX(tm)-6350 Six-Core Processor (family: 0x15, model: 0x2, stepping: 0x0) If you need more info, please tell what you need. With the current mainline (rc6+), I have done the following reverts to get a bootable system: Revert "x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f, 60-7f)" This reverts commit fa564ad9636651fd11ec2c79c48dee844066f73a. Revert "x86/PCI: Fix infinite loop in search for 64bit BAR placement" This reverts commit 470195f82e4ea550b7c37736a12bf3fa565295ea.
