so, what is it - stable or not stable ?

if sometimes "this kernel correctly reboots the system", do you mean that
happens spontaneously, i.e. without being actively triggered ?

how can this box work fine then or at least being considered "stable" then ?

there is already an issue there, and if it behaves different with 2.6.30, it
may be that the newer kernel triggers the existing problem in a different 
way.

afaik, you can also bisect on a different (i.e. faster) box.

i think it would be more interesting if there is anything in dmesg on such lockup.
if not, maybe you can hook up a serial console or netconsole and trigger sysrq when 
you have another lockup.

I  have  a  dual  Pentium-3 system. It based on Asus CUR-DLS mainboard
with  2  Pentium-3EB  1000MHz (133 MHz FSB) installed. Also, i'm using
hardware  RAID  controller  3ware  Escalade 7506-4LP, installed in the
PCI-X  expansion  slot.  This  RAID is only one disk system in the box
(RAID-5 on 4 IDE HDD 120GB from Seagate).

Box  works  works fine and very stable under 2.6.29.5 kernel, although
it is angry of buggy MP table (see app. #2 below). But sometimes, this
kernel  correctly  reboots  the  system  at all, but this happens very
rarely.  In  most cases, nobody detects the box was rebooted. And this
is satisfactory for me.

But  under 2.6.30.x kernels box freezes without any alerts. TTL before
freezing  is  about 5-30 mins. I don't know why that shit happens. I'm
ready to send any debug informations about this custom trouble, but if
the specialists will request it with instructions for me.
