I patched 2.6.15.6 with this patch, and everything seems to be fully functional as far as the PATA drive on that controller is concerned. However, a few concerns: 1. The kernel raid autodetection doesn't work here. Though I'm not clear if it supports going across controllers. I set up a raid-1 array wtih a drive on my other controller, set the partition type to autodetect, but a reboot left my array with just the drive not on the promise card. 2. Currently my BIOS's ATA settings are "SATA mode" - I also have "PATA mode" "SATA+PATA mode". I tried SATA+PATA and I get a bunch of IRQ16 ignored messages, a few tracebacks, and a LOT of slowness. I also get 3 scsiI haven't tried the PATA mode. Note that my box has 82801EB/ER controller which is currently my primary contoller as well as the Promise PDC20378 which is what I'm using this patch for. Any help would be appreciated. -- Phil Dibowitz phil@ipom.com Freeware and Technical Pages Insanity Palace of Metallica http://www.phildev.net/ http://www.ipom.com/ "Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Suess --------------enig0A1E602BE5A3D6EAE62AE110 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFEOcfwN5XoxaHnMrsRAla9AKCEHo2eHHKJfiyqfDgEA6w1YB6E5wCffOUx DeQXr+0NXRwAwqOJ5a+QotI= =DGkJ -----END PGP SIGNATURE----- --------------enig0A1E602BE5A3D6EAE62AE110--
