serious problems with raid5 / promise controllers

[spekulatius]

hello all,

in the last two weeks i had some time to convert my debian file server to gentoo. i did this right after i compiled my desktop system, which has also been a debian one. what i want to say with this: i am not new to linux, but new to gentoo, so give heavy in depth answers

but one thing i am really new to. problems with my raid 5. all i did was putting the raid 5 software array out of my server, reinstalled the whole system and compiled the xfs-sources for my kernel. i have a persistent superblock array, therefore i do not need a raidtab at the moment. the array was properly recognized, the devices of the disks have changed a bit, because i renewed the mainboard beforehand.

ok. now my problem. the array rebuilds far to often. it is ok that it does so if someone changes the devices and the beast wants to check itself. but it does this every reboot. it takes around 35 minutes, thats ok for its size but i think this is not necessary.

therefore i studied dmesg and found out the following:

what i forgot:

rebooting is nearly not possible. the init message appears, and thats it. kill command cannot be seen. just as an additional information.

thx so far.
