New kernel 9.1 informs me to report wbwd0 to FreeBSD

[BBLister]

Hi,

I upgraded to 9.1 ( 9.1-STABLE FreeBSD 9.1-STABLE #0 r251140: )  today and my 
dmesg kernel prints:

wbwd0: DevID 0x60 DevRev 0x12, please report this.
wbwd0: DevID 0x60 DevRev 0x12, please report this.
wbwd0: Unknown Winbond/Nuvoton model at port 0x2e-0x2f on isa0
wbwd0: Before watchdog attach: Watchdog enabled. Watchdog fired. Scaling by 1s, 
timer at 255 (=255s left). CRF5 0x00 CRF7 0xff


I am willing to provide any help necessary.

Regards,

BB

Question about kernel panic

[BBLister]

Greetings,

A server of mine kernel panicked and in the serial console it prints non stop 
these messages which
are repeated again and again..

avail memory = 8243830784 (7861 MB)


This machine will be rebooted on Monday, so from the time being I can only 
watch these messages repeated
again and again. This server is mainly used for virtualization (virtualbox) and 
has ZFS, on a Sil 3112 and
Intel 6300ESB SATA150 Controllers. I think that either the Sil controller or 
memory exhaustion due to ZFS and
virtualbox has occured.


How can I figure out what has really happened? Can I issue any command from the 
serial console?



Thank you

Serial Console activation causes system freeze (8.2-Stable)

[BBLister]

Greetings,


Ι have followed the guide about setting up the serial console:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ppp-and-slip.html

Ι have done this many times with no problems to other servers.

For the first time I have a very strange problem in this particular server: 
After seeing some kernel messages, Ι see garbage characters, the machine hangs 
completely and only a hard reset can be done. 
The garbage characters appear just before the uart initilization.

The last messages that I can see in the serial console:



atapci2: Intel 6300ESB SATA150 controller port 
0xa800-0xa807,0xa480-0xa483,0xa400-0xa407,0xa080-0xa083,0xa000-0xa00f irq 18 at 
device 31.2 on pci0
atapci2: [ITHREAD]
ata5: ATA channel 0 on atapci2
ata5: [ITHREAD]
ata6: ATA channel 1 on atapci2
ata6: [ITHREAD]
pci0: serial bus, SMBus at device 31.3 (no driver attached)
acpi_button0: Power Button on acpi0
atrtc0: AT realtime clock port 0x70-0x71 irq 8 on acpi0
atkbdc0: Keyboard controller (i8042) port 0x60,0x64 irq 1 on acpi0
atkbd0: AT Keyboard irq 1 on atkbdc0
kbd0 at atkbd0

atkbd0: [ITHREAD]
�� ��?�  ��?� ��?� 
��?M/���~/�~���M/�~���M�{�{�?'�'?���?u��u~^D

== at this point the whole machine freezes! (notice that
in the previous case the kernel hangs before any getty is initialized)


If I disable the serial console in loader.conf and boot.config then I have 
normal boot:


atkbd0: [GIANT-LOCKED]
atkbd0: [ITHREAD]
uart0: 16550 or compatible port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
uart0: [FILTER]
