Issue #2686 has been reported by peeter. ---------------------------------------- Bug #2686: kernel 3.8.1 freezes and panics at boot http://bugs.dragonflybsd.org/issues/2686
* Author: peeter * Status: New * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- DFly 3.6.x x86_64 boots and runs fine on my laptop (macbookpro5,5), the 3.8.1 install iso freezes at boot. (acpi/ehci disabled in both cases.) These are the last lines before freezing [boot_verbose=YES]: --- --- pci0: <processor> (vendor 0x10de, dev 0x0aa3) at device 3.5 irq 14 ohci0.pci0.pcib0.legacy0.nexus0.root0 ohci0: <nVidia nForce MCP79 USB Controller> [tentative] mem 0xd3488000-0xd3488fff irq 11 at device 4.0 on pci0 ohci0: Reserved 0x1000 bytes for rid 0x10 type 3 at 0xd3488000 ---FREEZE--- Since 3.6.x boots and runs fine (with acpi disabled) on this machine, I thought the freeze was related to the new usb. So upgraded 3.6.2 to 3.8.1 via git, did buildworld and buildkernel with WANT_OLDUSB=yes in /etc/make.conf. The system now panics at boot, showing [boot_verbose=YES]: ---3.8.1-oldusb--- fwohci0: <1394 Open Host Controller Interface> [tentative] mem 0xd3100000-0xd3100fff irq 7 at device 0.0 on pci4 fwohci0: latency timer 0 -> 32. fwohci0: cache size 64 -> 64. fwohci0: Reserved 0x1000 bytes for rid 0x10 type 3 at 0xd3100000 ---panic--- and then giving the db> prompt but because it freezes, or at least the keyboard freezes, I can't call dumpsys. So unfortunately there's no crash dump. I could then boot and run the system with the old 3.6.2 kernel. Further: since fwohci0 was the last line in the previous message, I recompiled the 3.8.1 kernel without firewire: --- # FireWire support #device firewire # FireWire bus code #device sbp # SCSI over FireWire (Requires scbus and da) #device fwe # Ethernet over FireWire (non-standard!) --- This causes kernel panic much later in the boot at umass and gives a db> prompt that is functional but call dumpsys returns only 0 and there is no still no core dump. I also tried booting FreeBSD 10.0 to see how the (new) usb stack fares. It boots fine. I attach the verbose dmesg for both FBSD 10 and DFly 3.6.2 just in case. I wonder if there's a way to get a debug or dumpsys for 3.8? Could vkernel help or is it isolated from hardware?
