Welcome to the Gentoo forums.
If you build the same configuration for v6.6.21, but disable ThinLTO and disable CFI, does the error appear? This would help to rule out a compiler bug.
The disassembled code looks quite simple, so I think that it is strange that this would fail. | Code: | 0: 48 3d 01 f0 ff ff cmpq $0xfffffffffffff001,%rax
6: 73 01 jae 9 <a+0x9>
8: c3 retq |

rebuilt the kernel with
| Code: | CONFIG_LTO_NONE=y
# CONFIG_LTO_CLANG_THIN is not set
# CONFIG_CFI_CLANG is not set |
also invalid opcode
note that the kernel is loading from module_blacklist=radeon
also new enabled values in the kernel 6.6.21 compared to 6.1.74 (maybe some of this has an effect)
| Code: | CONFIG_CACHESTAT_SYSCALL=y
CONFIG_FB_DEVICE=y
CONFIG_HID_SUPPORT=y
CONFIG_I2C_HID=y
CONFIG_LEGACY_TIOCSTI is not set
CONFIG_RANDOM_KMALLOC_CACHES=y
CONFIG_X86_USER_SHADOW_STACK=y
CONFIG_DEBUG_PREEMPT is not set
CONFIG_DRM_ACCEL is not set
CONFIG_SLUB_TINY is not set |
according to recommendations
https://forums.gentoo.org/viewtopic-t-1112778.html
P.S.
Please help, I haven’t been able to solve this problem for two months now, I’ve rebuilt the kernel several times since 6.6.13, including from gentoo-sources code and using GCC (even monolithic).
Kernel 6.6 is loaded only if the Radeon module is blacklisted. |
