Hello, world!\n
I have a new Opteron server based on Tyan Thunder K8S Pro (S882GNR) board. The storage is 3ware 7506 controller with 4 disks in RAID-5. The system has 4GB of RAM, and runs 2.6.1 kernel.
Problem 1: I have tried to run a test load (multiple kernel compiles using make -j4, copying a filesystem subtrees, etc), and I have noticed that all IRQs go to the CPU0 only. My /proc/interrupts says:
# cat /proc/interrupts CPU0 CPU1 0: 3188815 0 IO-APIC-edge timer 1: 10387 0 IO-APIC-edge i8042 2: 0 0 XT-PIC cascade 9: 0 0 IO-APIC-edge acpi 24: 46802 0 IO-APIC-level eth0 27: 384890 0 IO-APIC-level 3ware Storage Controller NMI: 903323 881935 LOC: 3188129 3188158 ERR: 0 MIS: 0
Is it normal? How can I set up some IRQ balancing (or at least hard-wire 3ware for CPU1 and eth0 for CPU0)?
Output of "dmesg" is at http://www.fi.muni.cz/~kas/tmp/dmesg-K8SPro.txt
Other problems are not so important or lkml-related:
Problem 2: the 3ware controller does not work correctly on the first PCI bus (slot 1 and 2) - in slot 1 it hangs under bigger load (e.g. an array rebuild), in slot 2 it hangs during boot in 3ware BIOS. It is probably not Linux-specific, but has anyone seen the same problem?
Problem 3: What the "PCI-DMA: Disabling IOMMU." message in dmesg output means?
Problem 4: Does Linux support the hardware sensors on this board? The i2c driver AMD8111 seems to be working, but what sensors driver should I use?
Problem 5: Is there a 3ware configuration program (tw_cli), which works on AMD64?
Thanks,
-Yenya
