And I've bought a new (expensive and high quality) 460W PSU and have exactly the same problems I had previously. (http://marc.theaimsgroup.com/?l=linux-kernel&m=113769509617034&w=2) and I'm not running Promise - I'm running sata_via and sata_sil (not as modules) David PS A Bit rushed as in a few hours I'm away on holiday for a week - if someone has time to have a scan through recent postings on the ide and raid lists they'll find quite a few problems that seem - to my untrained eye - to be similar. I've gathered some individuals together on the cc (hope that's OK) to see if the symptoms could be compared. If this isn't done next week then I'll try and do it when I get back (or maybe if I get net access next week) PPS Note that Mitchell's on verizon.net and mails to him from non-US ISPs may bounce (grr) -- - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
