If this happens when your HardDrive is quite busy - its probably normal -
as
the RT task has the priority over the HD handling.
As I already suggested this - you should look, if you have IDE HD, if
your DMA channels are turned ON (hdparm) (My drive looks like this)
# hdparm -v /dev/hda
/dev/hda:
multcount = 16 (on)
I/O support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 1 (on)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 0 (off)
This could free the processor from data transfer operations
