[DragonFlyBSD - Bug #2686] kernel 3.8.1 freezes and panics at boot

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2686 has been updated by peeter.


I tried DragonFly_RELEASE_3_8. Unfortunately, now it stops quite early at booting, almost the first page after reporting the CPU etc: 

--- ---
cryptosoft0: <software crypto> on motherboard
aesni0: No AESNI support.
padlock0: No ACE support.
rdrand0: No RdRand support. 
pcib0: <MTABLE Host-PCI bridge> pcibus 0 on motherboard
pci0: <PCI bus> on pcib0
MPTABLE: fixed interrupt routing for 0:3 INTA
MPTABLE: fixed interrupt routing for 0:3 INTB
MPTABLE: fixed interrupt routing for 0:4 INTA
---FREEZE---

and the same with boot_verbose=YES: 

--- ---
MPTABLE: fixed interrupt routing for 0:3 INTB
MPTABLE: 0:3 INTB routed to irq 14
IOAPIC: irq 14, gsi 14 edge/high -> level/low
found-> vendor=0x10de. . .
. . .
        map[10]: type Memory, range 32, base 0xd3488000, size 12, enabled
MPTABLE: fixed interrupt routing for 0:4 INTA
MPTABLE: 0:4 INTA routed to irq 11
IOAPIC: irq 11, gsi 11 edge/high -> level/low
unknown: Reserved 0x1000 bytes for rid 0x10 type 3 at 0xd3488000
ohci early: SMM active, request owner change
---FREEZE---

I commented out firewire in the kern config. Should I try with firewire?

Bug #2686: kernel 3.8.1 freezes and panics at boot
http://bugs.dragonflybsd.org/issues/2686#change-12100

* Author: peeter

----------------------------------------
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?

Thanks
