[Testbed-admins] Kernel panic on MFS freebsd.newnode

[Fernando Frota Redigolo <fernando@larc.usp.br>]

Hello,

I am in the process of reinstalling our Emulab instance with the new 5.0 
software. The problem that I am facing is that, when I try to boot the 
first node with the freebsd.newnode MFS (with ACPI disabled), a kernel 
panic happens, as show below:

atapci2: <Intel ICH7 SATA300 controller> port 
0x40c8-0x40cf,0x40e4-0x40e7,0x40c0-0x40c7,0x40e0-0x40e3,0x40a0-0x40af 
mem 0xc8300000-0xc83003ff irq 17 at device 31.2 on pci0
ata4: <ATA channel 0> on atapci2
ata5: <ATA channel 1> on atapci2
pci0: <serial bus, SMBus> at device 31.3 (no driver attached)
panic: vm_fault: fault on nofault entry, addr: c000b000
KDB: enter: panic
[thread pid 0 tid 0 ]
Stopped at      kdb_enter+0x2b: nop    

This happens with comconsole or vidconsole settings on loader.conf.orig 
(I suppose that with nullconsole as well, as the new node did not appear 
on the administrative pages). When booting with ACPI enabled, it hangs 
earlier during the boot.

I also tried booting with the freebsd MFS, and it completed just fine, 
without any problem. By comparing the two outputs it seems that the 
kernel panic happens during the serial port detection. Following is an 
excerpt from freebsd MFS boot output from the same point.

ata0: <ATA channel 0> on atapci1
ata1: <ATA channel 1> on atapci1
atapci2: <Intel ICH7 SATA300 controller> port 
0x40c8-0x40cf,0x40e4-0x40e7,0x40c0-0x40c7,0x40e0-0x40e3,0x40a0-0x40af 
mem 0xc8300000-0xc83003ff irq 19 at device 31.2 on pci0
ata4: <ATA channel 0> on atapci2
ata5: <ATA channel 1> on atapci2
pci0: <serial bus, SMBus> at device 31.3 (no driver attached)
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on 
acpi0
sio0: type 16550A, console
pmtimer0 on isa0
orm0: <ISA Option ROMs> at iomem 
0xc0000-0xcafff,0xcb000-0xcbfff,0xcc000-0xccfff,0xcd000-0xcd7ff on isa0
....

Is it possible to manually add the new nodes to the Emulab using the 
freebsd MFS or should I have to tweak the freebsd.newnode MFS ? Any 
other suggestions ?
