We have changed almost everything.
1. have tested kernels from 2.6.14 to 2.6.17
2. drbd from 0.7.14 to 0.7.21
3. changed machine to different vendor
4. changed SCSI disks to IDE
5. changed x86_46 architecture to i386
And all fail. All the time we get console lags.
The strangest thing is that when we run mysql on phisical 
device(/dev/sdaX) there is no lags.
I don't know how can I debug it.
