https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291915 Bug ID: 291915 Summary: server hung, login hangs on [zfs] Product: Base System Version: 15.0-RELEASE Hardware: arm64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dch@freebsd.org This issue is present *only* on/after OpenZFS 2.4.0 rc3 was merged, during 15.0 release cycle builds, and still in 15.0-RELEASE official. There is no additional information available in logs, dmesg, and a console login is impossible. I've had at least 10 of these since moving to 15.0-RELEASE, on varying aarch64 systems. I don't see this on amd64, but I don't have any amd64 servers in serious use anymore. Symptoms: everything hangs, but network & firewall still respond. Neither ssh nor ipmi console login is possible - see below: Instruction Set Attributes 1 = <> Instruction Set Attributes 2 = <> Processor Features 0 = <GIC,AdvSIMD,FP,EL3,EL2,EL1 32,EL0 32> Processor Features 1 = <MTE_frac> Processor Features 2 = <> Memory Model Features 0 = <TGran4,TGran64,TGran16,SNSMem,BigEnd,16bit ASID,4TB PA> Memory Model Features 1 = <8bit VMID> Memory Model Features 2 = <32bit CCIDX,48bit VA> Memory Model Features 3 = <> M FreeBSD/arm64 (straylight.skunkwerks.at) (ttyu0) login: root <----- we are expecting to get a password prompt here but it never arrives ^t repeatedly load: 1.52 cmd: login 4992 [zfs] 1352304.72r 0.00u 0.00s 0% 240k load: 2.60 cmd: login 4992 [zfs] 1352620.39r 0.00u 0.00s 0% 240k load: 2.60 cmd: login 4992 [zfs] 1352621.66r 0.00u 0.00s 0% 240k ...
