Submitted a post about this problem running on 6.3 (around 22nd Feb), I have
since reinstalled the system with 7.0 and it still displays the same behaviour,
ie, a large amount of interrupts. Top and dmesg below. Any help appreciated.
I also got 6.3 loaded onto an almost identical machine for an hour and it had the
same problem.
Regards,
Rob
