Hi, Thank you for fast reply. I'm sorry, on old server controller was installed on irq20, on new on irq21. The hardware is same on both servers, I use another slot, and error persist on both servers. So now: [root@gans /home/sg]# vmstat -i interrupt total rate irq1: atkbd0 3 0 irq16: ohci0 1 0 irq17: ohci1 ohci3 1 0 irq18: ohci2 ohci4 1 0 irq20: twe0 2392173 61 cpu0: timer 77623998 1999 cpu1: timer 77623962 1999 Total 157640139 4061 But after some time irq20 rate heavely increases to 100000+ and than system hangs... gstat shows disk usage avg. 20%. Don't know what to do, because I have used different kernels, and changed controller to new one.
