Well, now I have trashed my array :-) -> http://marc.theaimsgroup.com/?l=linux-raid&m=104811878405765&w=2
Btw., it spits out *lots* of messages when IRQ sharing is *disabled* in the kernel config and just dies quietly when it's *enabled* (having it dying before didn't mess up my array... ;)).

?! I'm using the onboard IDE for two CDROM drives and one smaller hard disk which I use rarely... and I didn't use any of these devices in the cases in which I had the described problems... Anyway, why should I connect a PS/2 mouse to the machine? Is it gonna solve all my problems at once? ;-) -- Mit freundlichen Gruessen / Yours sincerely Wolfram Schlich; Friedhofstr. 8, D-88069 Tettnang; +49-(0)178-SCHLICH - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
