https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270489 Bug ID: 270489 Summary: Laptop doesn't wake from suspend anymore with 13.2-RC5 Product: Base System Version: 13.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: email@example.com I've upgraded from 13.2-RC3 to 13.2-RC5 (RC4 was too fast for me to try it!) and my laptop stopped waking up from suspend -- when I open the lid nothing happens and I need to hard reboot it. Fortunately, I still have a booenvironment with -RC3. Looking at the kernel logs since RC3, I suspect this is related with commit: commit 7622d3671cbef860d5dede0e4beace8fd152cd87 Author: Konstantin Belousov <kib@FreeBSD.org> Date: Fri Mar 17 15:02:03 2023 +0200 amd64: properly recalculate mitigations knobs after resume But this is only a guess, of course. Here's what what's on dmesg about my T490 laptop CPU: CPU: Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz (1800.00-MHz K8-class CPU) Origin="GenuineIntel" Id=0x806ec Family=0x6 Model=0x8e Stepping=12 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x7ffafbbf<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,EST,TM2,SSSE3,SDBG,FMA,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,x2APIC,MOVBE,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND> AMD Features=0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> AMD Features2=0x121<LAHF,ABM,Prefetch> Structured Extended Features=0x29c67af<FSGSBASE,TSCADJ,SGX,BMI1,AVX2,SMEP,BMI2,ERMS,INVPCID,NFPUSG,MPX,RDSEED,ADX,SMAP,CLFLUSHOPT,PROCTRACE> Structured Extended Features3=0xbc000600<MCUOPT,MD_CLEAR,IBPB,STIBP,L1DFL,ARCH_CAP,SSBD> XSAVE Features=0xf<XSAVEOPT,XSAVEC,XINUSE,XSAVES> IA32_ARCH_CAPS=0x20c2b<RDCL_NO,IBRS_ALL,SKIP_L1DFL_VME,MDS_NO> VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID TSC: P-state invariant, performance statistics (Not sure if this is useful or where to get more useful information.) Now, maybe this is a different issue, or maybe it is the same... but when I tried to compile a kernel with the above commit reverted in the 'releng/13.2' branch (and running -RC5), I had an hard-reboot (!). As I said, I'm not sure if that's a different issue, because I had the 4 CPUs at 100%, so maybe it was an overheating issue. When I booted back into RC3 kern.msgbuf had the following: Fatal trap 9: general protection fault while in kernel mode cpuid = 3; apic id = 06 instruction pointer = 0x20:0xffffffff810a253a stack pointer = 0x28:0xfffffe012cdcbc20 frame pointer = 0x28:0xfffffe012cdcbd60 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 15190 (cc) trap number = 9 panic: general protection fault cpuid = 3 time = 1679950971 KDB: stack backtrace: #0 0xffffffff80c53dc5 at kdb_backtrace+0x65 #1 0xffffffff80c06741 at vpanic+0x151 #2 0xffffffff80c065e3 at panic+0x43 #3 0xffffffff810b1fa7 at trap_fatal+0x387 #4 0xffffffff81088e78 at calltrap+0x8 #5 0xffffffff80f5645f at vmspace_exit+0x7f #6 0xffffffff80bbc841 at exit1+0x591 #7 0xffffffff80bbc2ad at sys_sys_exit+0xd #8 0xffffffff810b289c at amd64_syscall+0x10c #9 0xffffffff8108978b at fast_syscall_common+0xf8 Uptime: 11m17s Dumping 1470 out of 24183 MB: (CTRL-C to abort) ..2% (CTRL-C to abort) ..11%..21% (CTRL-C to abort) ..31% (CTRL-C to abort) ..41%..51% (CTRL-C to abort) (CTRL-C to abort) ..61%..71%..81%..91% (CTRL-C to abort) (CTRL-C to abort) ---<<BOOT>>--- -- You are receiving this mail because: You are the assignee for the bug.
