And of course, switching external cache back on in the BIOS fixes this.
Sorry for the missteak.

Oh, and I should mention it also fixes the problem of the interactive
performance going out the window for quite a while under heavy I/O load
(eg, copying untarred kernel source tree to backup) Not sure how bad

us poor bastards with IDE (even with UDMA/33).
