actually, whilst i was sending you the ksymoops output i searched and googled a bit and saw that hotplug seems to crop up more than once in conjunction with the worker_thread 'oops'. I disabled that and recompiled (its an athlon, so it doesnt take long), re-lilo'd and booted the 'new kernel'. This was the only kernel parameter i changed and now i can mount the raid5 and it is marked 'clean' after the rebuild. i am currently using it as well, playing mp3's from it, so its looking good. that being said, there -was- a symoops on mount, although it wasnt enough to stop it from mounting, and it appears to be the same as the last one (same sort of ksymoops output :\ i will try the patch tomorrow and let you know, i am jst glad that the drive is working (for now :) thanks for the help Stef - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
