https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270943 Bug ID: 270943 Summary: Complete system freeze on Asus dual socket AMD 7742 system Product: Base System Version: 13.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: email@example.com Created attachment 241605 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=241605&action=edit dmesg.boot For this system I have a dual socket 7742 system (128 total real cores, 128 threads) that will completely lock up the system in under an hour if left idle. By "lock up", this means: * Console unresponsive (no keyboard/USB/numlock) * Networking unresponsive (no pings, no arps, nothing) Like it's "jumping to self" with all interrupts disabled. The system needs to be reset or power cycled. I have tried the following distributions over the last few months with the same results: FreeBSD 13.2-RELEASE releng/13.2-n254617-525ecfdad597 GENERIC amd64 FreeBSD 13.1 FreeBSD 13.0 FreeBSD 12.3 Several memstick images of 14.0 since December 2022 Other notes: * The lockup is guaranteed. I've never had it not lock up when left idle. Always locks up in <1 hour (usually in 10-20 minutes). * If I run a "stress" program, the system runs for days at a time without any observed lockups. If there's any significant system activity, it appears to not lock up. * At one point (on a 14.0 build) I was able to get the kernel debugger compiled in. When the system locked up, hitting the local USB keyboard sequence to get in to the kernel debugger worked. This also seemed to unlock the system, as after I exited the kernel debugger, the system was alive again. * I've installed the OSes on either 2GB M.2 Samsung SSDs *OR* on a Western Digital SN200 NVME disk. No changes in behavior. Storage does not appear to be a factor. * I've halved the memory and swapped DIMMs entirely. No change. System specs: Motherboard : Asus rs700a-e11-rs12u-wocpu009z CPUs : Dual AMD 7742 CPUs BIOS Version : 0901 BMC Firmware model : RS700A-E11-RS12U BMC Firmware version: 1.2.15 Installed ECC memory: 512GB Storage : Two Samsung EVO 980 TB M.2 SSDs, and a WD SN200 7.68TB NVME U.2 disk Video is the ASpeed AST2500, which supplies video for the system. I'd be happy to put this system on the internet and allow any and all interested parties access to it for troubleshooting/debugging.
