If memory serves me right, Turion64 sounds like an "old" CPU, right?
("old" for today CPU's rhythms of life means a mactufacturing date of
2005/2006)

Yes, there are many reports on that error:
http://www.google.com/webhp?complete=0&hl=en#q=debian+MP-BIOS+bug:+8254+timer+not+connected+to+IO-APIC&hl=en&tbo=1&complete=0&prmd=imvns&tbas=0&source=lnt&sa=X&ei=2RKbTrePHMfAswbhocmUBA&ved=0CAkQpwUoAA&bav=on.2,or.r_gc.r_pw.,cf.osb&fp=bd638b897581bb57&biw=1280&bih=888
But the relation between this message and the hard disk slowdown is

Yes please, the more accurate information you provide, the more changes for
a kernel hacker who reads your message can help you :-)
