I have 2.0.34 and 2.0.35 with SMP 1.1 and 1.4 BIOSes without any problem.
Sure this is not _the_ reason to go 2.1.xxx.

I saw a similar problem in one of our machines when the total memory was
specified in lilo.conf (is this your case?), although the live cycle was a
couple of hours (it depends on available ram and workload). Specifying
(1) MB less in lilo.conf solved the problem (related to bios shadowing, some
bioses can not be changed not to shadow).

If you are going to use SMP and 2.0.xx (I found 2.0.35 is really bad for
SMP,
2.0.33 and 2.0.34 performs a little better/longer), I strongly recommend you
2.0.36 (is en pre19 at the moment but it is rock solid in my machine). It
is a big step from 2.0.35, recognizes all available ram also has _much_
better adaptec drivers.

Good luck.

PS: Did anyone see the report of the contract between TurboLinux and Adaptec
to develop "better Adaptec" drivers for Linux? What does it mean? Are they
going to improve Doug drivers or start from scracht?
