Message-ID: <8d158e1f0702050300s56dd1d9cg76e13b3a13f07de7@mail.gmail.com> Date: Mon, 5 Feb 2007 12:00:35 +0100 From: "Patrick Ale" <patrick.ale@...il.com> To: Stephen.Clark@...lark.us Cc: "Robert Hancock" <hancockr@...w.ca>, linux-kernel@...r.kernel.org Subject: Re: hdparm for lib_pata Good morning all, About the reason as of why it drops to PIO mode, I might have found the reason for this, I am just not sure if what i found is related. When I opened my Athlon XP machine, took the cables out and replaced them for new cables, I found out that my southbridge fan wasnt spinning anymore, at all. So my guess is that this chip is overheated at some point and starts causing problems. Now, it was always my comprehension that the southbridge does indeed control the ATA controller but only the onboard one, so even if the chip is having heat problems, my PCI add-on cards should still work on full UDMA100 speed, right? I am re-assembling my athlon board again today, and as soon as I get the falling back to PIO mode errors again in dmesg I'll forward you the messages, like you asked :) If someone could shine a light on my question about the southbridge, I'd really appriciate it, email me privately if you prefer. Thanks!
