Hello Ralf, Thank you very much for the quick response. I know you must be terribly busy with the server move, so I won't take up too much more of your time. I did find an old (possibly related) discussion you were involved in: http://www.linux-mips.org/archives/linux-mips/2006-09/msg00194.html I can't tell from the thread whether it was a problem seen on 2.6.16.29, but that might have been tip at the time. > It's a bug which should be fixed but nevertheless I > can highly recommend > something like a SiliconImage SATA controller - the > onboard PIO PATA > controller is so slow.

I probably should have used that approach instead of diffing .27 and .29 and narrowing the file list by hand. As it was, there were changes to non-MIPS platforms and devices I'm not using so those were easy to apply to .27. Also, there were many file changes for MT SMP support, and *most* (but not all) of those changes were wrapped with conditional compiles, so those were also easy to apply. I knew once I got to these five files I was in some interesting code that could point to the problems I'm seeing. > Later kernels do run on bcm1480 which is close > enough. By "later kernels", do you mean 2.6.16.60 or different kernel branches? Perhaps, but I'm seeing identical failures in .29 and .60, although that could be misleading. I do see significant SMP-related changes in c-sb1.c between .29 and .60, and I am running in SMP. I wish there was an easy way to know whether it's in the same code. Anyway, in the interest of time I may revert to .27 which appears to work. I don't need any of the MT SMP related changes that followed, and perhaps I can live without the enhancements between .27 and .60 for now.
