G'day,
I am testing a new server with a Supermicro X7SBA motherboard
and TE405 cards. When I load Dahdi and run dahdi_cfg I get
the following errors:
kernel: Uhhuh, NMI received for unknown reason b1 on CPU 0
You probably have a hardware problem with your RAM chips
Dazed and confused, but trying to continue
The reason codes I have seen are a0, a1, and b1.
The problem only occurs once and the system seems to work fine
after that. If I cat /proc/interrupts, I only see 1 NMI and it is only
for CPU 0.
I also saw the same error with this computer when I tried
an older version of Zaptel.
I ran memtest86 overnight on the server and had 0 failures so I
doubt that the problem is RAM.
Computer: Supermicro X7SBA, Intel E5300, 2xWD SATA, Bios 1.2a
XGI Tech video
O/S: CentOS 5.4, 2.6.18-164 i386 SMP
most updates applied
Dahdi: complete 2.3.0+2.3.0
I have tried options per the Digium page: http://kb.digium.com/entry/64/
nmi_watchdog=0
pci=noacpi nmi_watchdog=0
pci=norouteirq acpi=off pci=noacpi noapic vga=0x31a nmi_watchdog=0
<- would not boot
Any suggestions on what else I could try?
Also, on this same computer when using the Zaptel driver, I am getting
a lot of SIS errors from the wct4xxp driver:
!!!SIS Waiting before cmd 08
!!!SIS waited 1 loops
Thanks,
