This bug is also filed at http://bugme.osdl.org/show_bug.cgi?id=3D1217 I did some more tests and the bug still exists in 2.6.0-test7-bk1. I found= =20 that running the hpt372 with a 40pin cable ATA33 is roughly twice as fast f= or=20 writes as using the 80pin cable ATA133, there is something definitely wrong= =20 here. Both modes are significantly slower than when using the same 80pin ca= ble=20 ATA100 on the Intel ICH5 controller.=20 =20 BTW - I think the ICH5 driver has a problem as well. When I tried to use th= e=20 same 40pin cable I used for the hpt372, to test ATA33 mode, the kernel spit= =20 out a lot of messages about CRC errors.=20 =20 Chris Cheney hpt372 bios 2.35 40pin cable=20 ----------------------------=20 Version 1.03 ------Sequential Output------ --Sequential Input- --Ran= dom- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --See= ks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec= %CP calc 2G 18668 66 19857 7 10159 3 19851 59 30713 3 186.5= 0 ------Sequential Create------ --------Random Create----= ---- -Create-- --Read--- -Delete-- -Create-- --Read--- -Dele= te-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec= %CP 16 3182 98 +++++ +++ +++++ +++ 3098 94 +++++ +++ 8743= 99 calc,2G,18668,66,19857,7,10159,3,19851,59,30713,3,186.5,0,16,3182,98,+++++,= +++,+++++,+++,3098,94,+++++,+++,8743,99 hpt372 bios 2.35 80pin cable=20 ---------------------------- Version 1.03 ------Sequential Output------ --Sequential Input- --Ran= dom- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --See= ks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec= %CP calc 2G 9689 34 9252 3 7228 2 20321 61 43606 4 189.8= 0 ------Sequential Create------ --------Random Create----= ---- -Create-- --Read--- -Delete-- -Create-- --Read--- -Dele= te-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec= %CP 16 3113 95 +++++ +++ +++++ +++ 3107 94 +++++ +++ 7596= 85 calc,2G,9689,34,9252,3,7228,2,20321,61,43606,4,189.8,0,16,3113,95,+++++,+++= ,+++++,+++,3107,94,+++++,+++,7596,85 ich5 80pin cable=20 ---------------- Version 1.03 ------Sequential Output------ --Sequential Input- --Ran= dom- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --See= ks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec= %CP calc 2G 27586 98 48814 19 21368 6 24561 74 51393 4 185.2= 0 ------Sequential Create------ --------Random Create----= ---- -Create-- --Read--- -Delete-- -Create-- --Read--- -Dele= te-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec= %CP 16 3211 99 +++++ +++ +++++ +++ 3241 99 +++++ +++ 8650= 100 calc,2G,27586,98,48814,19,21368,6,24561,74,51393,4,185.2,0,16,3211,99,+++++= ,+++,+++++,+++,3241,99,+++++,+++,8650,100 --JP+T4n/bALQSJXh8 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQE/hmuy0QZas444SvIRAiS/AKCln/2VIe/QvN/djsd4F2JZGM4EJACgnuKm q8cB7MT6EO9aBTOgklMjLS8= =ZNd0 -----END PGP SIGNATURE----- --JP+T4n/bALQSJXh8--
