Hi, I have posted a couple of times in the past to no avail... I have an Intel 31244 SATA controller that is supposed to work with the sata_vsc driver module... It does in fact, almost....
You can insert the module in a running kernel and after barking as follows (once for each disk attached) it runs just fine. Jan 24 13:55:37 linux kernel: irq 3: nobody cared!

Same when booting with the module builtin to a monolithic kernel.... To facilitate helping me, I have gathered the requisite stuff and posted it on my website as follows: http://www.dpsims.com/~dpsims/31244/ If someone would be so kind as to help me, I would be willing to provide access to the machine in question for testing, etc... I believe the problem is caused by the Intel 31244 having multiple ways of sending interrupts... The Intel documentation is located at: http://www.dpsims.com/~dpsims/31244/31244_developers_guide.pdf and I draw your attention to section 5.8 and 5.9.... The code for the sata_vsc.c from kernel 2.6.10 can be found at http://www.dpsims.com/~dpsims/31244/sata_vsc.c I would make this work myself if I had the required skill sets... but I don't.... Thus I am reduced to pleading ;) Please help me. I will try to contribute whatever I can... quickly test.... /etc...
