Thank you for your quick answer
I applied the patch to 2.6.16.9 source, I mean, gentoo-sources-2.6.16-r7 to
be exact
But the kernel showed the very same message:
<<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>>
Recovery code sleeping
Recovery code awake
aic7xxx_abort returns 0x2002
aic7xxx_dev_reset returns 0x2002
Recovery SCB completes
Any way I appreciate the patch you wrote for me.

OK, try this ... I think it will correct for the Western Digital
problem.
