As some of you may have noticed, the Linux 2.0 development has reached the
so-called "pre2.0" kernels, which are test-kernels before the final 2.0
release meant to shake out the last few bugs so that we don't get caught in
the "x.0 syndrome".
These pre2.0 kernels are available at the normal kernel ftp sites: the two
sites I directly upload to are
but you may want to (nay, make that "you really should") check out a Linux
mirror site nearer to you before you get it from either of these sites.
The current pre2.0 kernel is linux-pre2.0.7 (you'll know that it's a pre2.0
by the fact that the kernel reports the version number as "1.99.x"), and that
will be the last pre2.0 for some time - I'll be away in Germany for a week.
As such I hope you will all test it out exhaustively. As I'll be away from
my mail, I hope any potential problems can be discussed on the mailing lists
and newsgroups, but I hope to get the problem reports Cc'd to me if you think
the seriousness warrants it. But before mailing a bug-report, see:
NOTE! 2.0 has some differences from 1.2.13, and if you are upgrading from
that release (or just generally from an older kernel) you should read the
linux/Documentation/Changes file carefully, as that tries to explain some of
the problems you may encounter due to those differences. It is counter-
productive to send me a bug-report about "top dumps core", because that's a
known problem with a known (user-level) fix.
Also note that you should have a reasonably new version of gcc: gcc-2.5.8
is known to produce incorrect code under certain circumstances, and gcc-2.7.2
is recommended (the kernel will refuse to compile with anything older
I hope people will take the opportunity to test this out, as the more
testing it gets the more likely we are to find any obscure bugs. If you feel
too worried about it, I can only say that our computer science department is
now running pre2.0 on both the web- and ftp-server and on the department mail
