Hmmm, Interesting. Thank you for testing. I have a slightly different chipset (X370-PRO). Wouldnt think that would make a difference. And considering the Epyc also crashes-- although that takes a LOT longer, I am not sure whats going on. There is yet another BIOS update for this board. So trying with that. The vmm driver does report things a little different, so we will see ivhd0: <AMD-Vi/IOMMU ivhd with EFR> on acpi0 ivhd0: Flag:b0<IotlbSup,Coherent> ivhd0: Features(type:0x11) MsiNumPPR = 0 PNBanks= 2 PNCounters= 0 ivhd0: Extended features[31:0]:22294ada<PPRSup,NXSup,GTSup,IASup> HATS = 0x2 GATS = 0x0 GLXSup = 0x1 SmiFSup = 0x1 SmiFRC = 0x2 GAMSup = 0x1 DualPortLogSup = 0x2 DualEventLogSup = 0x2 ivhd0: Extended features[62:32]:f77ef<USSup> Max PASID: 0x2f DevTblSegSup = 0x3 MarcSup = 0x1 ivhd0: supported paging level:7, will use only: 4 ivhd0: device range: 0x0 - 0xffff ivhd0: PCI cap 0x190b640f@0x40 feature:19<IOTLB,EFR,CapExt> The load also matters. Try with 2 FreeBSD instances. I am not able to quickly crash with just one. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 x203 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada
