Hello Storage Controller Experts, I am writing this mail to you to request your assistance in resolving a functionality regression in my sata_nv controller driver in recent Linux kernels. I am hoping you can assist me in finding a solution to this because my TV tuner card is dependent on some fixes in the newer kernels but using the newer kernels causes some of my storage volumes to be unreadable, thereby putting me in a catch-22 situation. Please let me know if any other omitted information is required for diagnostics. Sorry for the delay in contacting you promptly but: 1) I attempted to contact the maintainer listed directly in the driver source code and he never replied. 2) I was holding out the mistaken hope that the problem was transient and would be resolved without my intervention. Disclaimer: I am sure one of you will notice I am using the nvidia binary video graphics driver on this system... I say this to provide full disclosure that I am aware of the implications and of course I am willing to disable the driver for diagnostic purposes. I have tried running the system without the driver loaded and did not find any change in behavior but if you think it is part of the problem please let me know. I am using the Supermicro H8DCE motherboard. Some (not all) of the SATA channels quit working due to some kind of resource conflict when I upgrade to any kernel above 2.6.20.xx series, in my case I am running 2.6.20.21 SMP x86_64 presently. The boot error which appears in dmesg for the missing SATA channels on 2.6.23.12 is pasted below and a compressed copy of my configuration file for 2.6.23.12 is attached. The dmesg for 2.6.20.21 is attached and note the configuration is the same except for being run through make oldconfig.
