Seeing as prefetch is not really suggested below 4G of RAM and as well on i386 it is not really much concern to me ATM. Whatever did change "Not in the ZFS code" & "Not in r216162 or r216455" has effected prefetch on i386 directly though or at least as far as I can see for the moment. As of right now Ill look into a few other commits starting with r216305 which was a MFC of r216194. I would like to see this resolved as I currently only have i386's to run from unless that is someone would like to donate some hardware ;) Regards, - -- jhell,v -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJNDD0AAAoJEJBXh4mJ2FR+SqIH/jkWf8Z69lKC3wlSYjwwNqTL gX/rEuAU/2xOQj2bKR4/BEfeNXtSy9n47IbbCZApGuBABf2lkytSUk2n1XgQ1sB1 GRJl8gCm5BtmhZh0oTc9CIwUcJy+h/w3dU34WXp5riegk0MwpPJlbx9JX4huC+6s j+wG0oJpxJZq1v/0uWM7ks1D6yYzgBXFyp9j+8ZGoeeXIeraqglj57eB0+Ck1Jq2 JjQ9uLTqnkLS2Zzf/Vgbju4O4bV6geAd+j6Td6Fwt+c3yHCWOHSFQcakyrdJzntl feWJPAl9ZZSGBhvdAH4pumLt01BVyESIe/rsbtD68pAIGWqxrL3NsI6bIDg3cvI= =apgr -----END PGP SIGNATURE-----
