Just out of curiosity, how long did you let the raid 5 array "build" in the first place? I have seen similar problems (couldn't unmount etc) when the array has not completed the build process. The larger the array, the longer the build time (can take hours?). Patience is *definitely* a virtue when working with raid 5 arrays. I had a similar setup (3 Ultra 100 TX2 cards + 6 WD drives) that I could never get to work *reliably*. I would get a similar dmesg file. Note the last controller stating "PDC20267: (U)DMA Burst Bit DISABLED" and ide6 and ide7 being set to PIO (*not* UDMA 100) mode. I got this same message. The array might boot up fine, but virtually every time within a few hours one or both of the drives on the last controller would drop down to PIO mode and I/O to the array would drop to the 2-3 MB/sec range (as measured by hdparm -Tt) instead of the normal 30 MB/sec range. Bottom line, I *never* was able to get 3 Promise Ultra100 TX2 cards working *reliably* in the same system. I just recalled, I was never able to get 3 Ultra100 TX2 cards working *at all* in the same system. What I did to get it functioning (and giving the results described above) was to use 2 Ultra100 TX2 cards, and 1 Ultra100 card. I also tried the promise SuperTrak 100 with little or no success under linux. I finally shelled out a few extra bucks and purchased a 3Ware board and have been *very* happy with it ever since. Be willing to cut your loses before you spend too much more time trying to get the three controllers to work together..
