Hi,
a few days ago i installed a server with the latest RC. It has an mvs
based controller, attached to it are 6 disks in a RAIDZ, the server has
8GB of RAM and is running amd64. The CPU is a single core Xeon with HT
turned on.
This morning it hanged for the 2nd time, this time i managed to capture
the panic massage:
Fatal trap 19: non-maskable interrupt trap while in kernel mode
Fatal trap 19: non-maskable interrupt trap while in kernel mode
cpuid = 1; cpuid = 0; apic id = 01
apic id = 00

trap number = 19
panic: non-maskable interrupt trap
cpuid = 0
Here are some details about the controller.
mvs0@pci0:6:1:0: class=0x010000 card=0x11ab11ab chip=0x608111ab rev=0x09
hdr=0x00
vendor = 'Marvell Semiconductor (Was: Galileo Technology Ltd)'
device = 'MV88SX6081 8-port SATA II PCI-X Controller'
class = mass storage
subclass = SCSI
After the panic the server just hangs, so i was not able to get a dump
or get a backtrace. I'm just building a custom kernel with debugging
turned on.
Anything i could do in the meantime?
Thanks,
Florian
