	Thanks (in my system - Fedora Core 0.96 - it is "irqbalance", without
the "d" at the end, from kernel-utils package). When I ran it it migrated
some IRQs to CPU1, so this is probably OK. Thanks.

	I will try tomorrow.

	This is what I expected. OK.

	Exactly. Thanks for the hint.

	Does not work:

ioctl32(tw_cli:32216): Unknown cmd fd(3) cmd(0000001f){00} arg(080dd2e0) on /dev/twe0

I have asked 3ware.

	Thanks for your help,
