Hi,

my system running snv_50 is often very slow, the mouse cursor is 'jumping' on 
the screen as if the system is very busy and by switching workspaces the 
desktop needs several seconds to be redrawn. The problems seems to be the huge 
amount of interrupts. 

intrstat:

      device |      cpu0 %tim
-------------+---------------
       ata#0 |         2  0.1
  audio810#0 |     52857  3.0
      ehci#0 |         0  0.0
       nfo#0 |     52857  3.3
   pci-ide#1 |         0  0.0
   pci-ide#2 |    105715  3.8

nfo#0 is the on-board network interface. I've read something about false 
"interrupt polarity" in the DSDT ACPI table but I don't know which changes I 
have to make to the table.

The system specs are

MSI K8N Neo Platinum Motherboard
Nvidia nForce 3 2050Gb Chipset (Audio & NIC on-board)
MSI RX9250 ATI Radeon Graphics Card
AMD Athlon 64 3000+
AWARD Bios V2.1 (The latest I could find at MSI's webpage)
3xSATA HD's (1 UFS, 2 ZFS)

I'd appreciate any help or suggestion. 

Thanks,

             snafoo
