Hello list,
I have observed a strange slowdown with the 2.6.18 kernel in VMware.
This happened both with the SUSE flavor and with the FC6 installer CD
(which I am trying right now). In both cases, the kernel "takes its
time" after the following text strings:
* Checking if this processor honours the WP bit even in supervisor mode... Ok.
* Checking 'hlt' instruction... OK.
What's with that?
Thanks. It is perhaps the jiffies calibration taking a while because of
the precise timing loop. Are you reasonably confident that it is a
regression in performance over 2.6.17? The boot sequence is pretty
complicated, and a lot of it is difficult / slow to virtualize, so it
could just be alternate timing makes the boot output appear to stall,
when in fact the raw time is still about the same. I will run some
experiments.
