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.

Kind Regards
