No problem. Interestingly, applying this "rollup" patch prevented 2.6.12-ck4 from crashing my rather nondescript desktop machine during boot. Con Kolivas changed HZ from 1000 to 864 in this patchset and it has been causing problems (I do not think that 864HZ is a convenient value in practice). I'm not exactly certain as to how the crash is rectified by the changes in this patch though. > What do you mean with "real" SMP? > Is that real as opposed to fake==Hyperthreading, or real as in "more > than a handful of nodes"? Hyperthreading does not count as far as I'm aware so yes, I specifically meant that. But obviously the problem may be far worse with a greater number of nodes. > strangely enough, the gentoo patch applies cleanly to my 2.6.12.3 tree, > the other does not. Sorry about that; the name is a little misleading. The principal difference between the patch that applies against a stock 2.6.12 and the "gentoo" one is that the gentoo tree incorporates a patch that modifies the tpm.h header. This patch was actually added in the regular stable tree so really the patch that you are using ought to be called "2.6.12.3-timing-fixes-rollup.patch". > Will report from dual-AthlonXP 1800 system soon. Thanks. Also, I forgot to mention this (and so does the help text for that matter) but reducing HZ also reduces power consumption. In particular, this may be observed on laptops. Laptops can be strange beasts and reducing HZ can apparently solve other strange problems with some machines such as audible noises when entering/leaving power-saving states and interference with the sound output.
