Hello. I've had this machine for eons and it went through almost every FreeBSD version in the last years without a hitch. After upgrading to 11.1, however, it will often (not always) hang on boot. Some extract from dmesg (I think these are the relevant parts): > ... > FreeBSD 11.1-RELEASE-p6 #1 r327994M: Mon Jan 15 09:50:57 CET 2018 > root@alamar.ventu:/usr/obj/usr/src/sys/ALAMAR amd64 > FreeBSD clang version 4.0.0 (tags/RELEASE_400/final 297347) (based on LLVM 4.0.0) > ... > ahci0: <AMD SB7x0/SB8x0/SB9x0 AHCI SATA controller> port 0xa000-0xa007,0x9000-0x9003,0x8000-0x8007,0x7000-0x7003,0x6000-0x600f mem 0xfe6ffc00-0xfe6fffff irq 22 at device 17.0 on pci0 > ahci0: AHCI v1.10 with 6 3Gbps ports, Port Multiplier supported > ahci0: quirks=0x22000<ATI_PMP_BUG,1MSI> > ahcich0: <AHCI channel> at channel 0 on ahci0 > ahcich1: <AHCI channel> at channel 1 on ahci0 > ahcich2: <AHCI channel> at channel 2 on ahci0 > ahcich3: <AHCI channel> at channel 3 on ahci0 > ahcich4: <AHCI channel> at channel 4 on ahci0 > ahcich5: <AHCI channel> at channel 5 on ahci0 > ohci0: <AMD SB7x0/SB8x0/SB9x0 USB controller> mem 0xfe6fe000-0xfe6fefff irq 16 at device 18.0 on pci0 > usbus0 on ohci0 > usbus0: 12Mbps Full Speed USB v1.0 > ohci1: <AMD SB7x0/SB8x0/SB9x0 USB controller> mem 0xfe6fd000-0xfe6fdfff irq 16 at device 18.1 on pci0 > usbus1 on ohci1 > usbus1: 12Mbps Full Speed USB v1.0 > ehci0: <AMD SB7x0/SB8x0/SB9x0 USB 2.0 controller> mem 0xfe6ff800-0xfe6ff8ff irq 17 at device 18.2 on pci0 > usbus2: EHCI version 1.0 > usbus2 on ehci0 > usbus2: 480Mbps High Speed USB v2.0 > ohci2: <AMD SB7x0/SB8x0/SB9x0 USB controller> mem 0xfe6fc000-0xfe6fcfff irq 18 at device 19.0 on pci0 > usbus3 on ohci2 > usbus3: 12Mbps Full Speed USB v1.0 > ohci3: <AMD SB7x0/SB8x0/SB9x0 USB controller> mem 0xfe6f7000-0xfe6f7fff irq 18 at device 19.1 on pci0 > usbus4 on ohci3 > usbus4: 12Mbps Full Speed USB v1.0 > ehci1: <AMD SB7x0/SB8x0/SB9x0 USB 2.0 controller> mem 0xfe6ff400-0xfe6ff4ff irq 19 at device 19.2 on pci0 > usbus5: EHCI version 1.0 > usbus5 on ehci1 > usbus5: 480Mbps High Speed USB v2.0 > atapci0: <ATI IXP700/800 UDMA133 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xff00-0xff0f at device 20.1 on pci0 > ata1: <ATA channel> at channel 1 on atapci0 > ... > ahd0: <Adaptec 29320 Ultra320 SCSI adapter> port 0xe800-0xe8ff,0xe400-0xe4ff mem 0xfebfe000-0xfebfffff irq 20 at device 5.0 on pci3 > aic7902: Ultra320 Wide Channel A, SCSI Id=7, PCI 33 or 66MHz, 512 SCBs > ahd1: <Adaptec 29320 Ultra320 SCSI adapter> port 0xe000-0xe0ff,0xd800-0xd8ff mem 0xfebfc000-0xfebfdfff irq 21 at device 5.1 on pci3 > aic7902: Ultra320 Wide Channel B, SCSI Id=7, PCI 33 or 66MHz, 512 SCBs > ... > ugen4.1: <ATI OHCI root HUB> at usbus4 > ugen1.1: <ATI OHCI root HUB> at usbus1 > ugen0.1: <ATI OHCI root HUB> at usbus0 > ugen6.1: <ATI OHCI root HUB> at usbus6 > uhub0: <ATI OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus4 > uhub1: <ATI OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus1 > uhub2: <ATI OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus6 > uhub3: ugen3.1: <ATI OHCI root HUB> at usbus3 > <ATI OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus0 > uhub4: <ATI OHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus3 > ugen5.1: <ATI EHCI root HUB> at usbus5 > ugen2.1: <ATI EHCI root HUB> at usbus2 > uhub5: <ATI EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus5 > uhub6: <ATI EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus2 > uhub2: 2 ports with 2 removable, self powered > uhub0: 3 ports with 3 removable, self powered > uhub1: 3 ports with 3 removable, self powered > uhub3: 3 ports with 3 removable, self powered > uhub4: 3 ports with 3 removable, self powered > uhub5: 6 ports with 6 removable, self powered > uhub6: 6 ports with 6 removable, self powered > ... > ugen5.2: <Generic Mass Storage Device> at usbus5 > umass0 on uhub5 > umass0: <Generic Mass Storage Device, class 0/0, rev 2.00/1.29, addr 2> on usbus5 > umass0: SCSI over Bulk-Only;

Often, after a few of daX and/or cdX are output, the machine hangs, the SCSI controller light staying on: sometimes it will spontaneusly reboot after several seconds, sometimes I'll have to press the reset button. There's no rules to how many times I have to try booting every morning: some days it starts right the first time, some days I have to reboot several times until it gets it right and goes ahead. While it might be an hardware problem (being the box quite old), the fact that it started doing this after a 10.3->11.1 upgrade is suspicious. Is there a known race-condition/LOR/whatever? Is there a way to get better info (e.g. some option to put in the kernel config or in /boot/loader.conf)? Should I enable DDB, INVARIANTS, WITNESS & co.? I'd like to avoid breaking performance, but I'll do if it's the only way. bye & Thanks av.
