I sampled swioltb in the range from 2k to 512k in steps of factor 2 and 4 M as a very large value. Except for 2k I get the same kernel bug in /home/smb/hardy-i386/ubuntu-2.6/debian/build/custom-source-xen/mm/bootmem.c:190 For 2k I get "low bootmem alloc... Kernel panic ... Out of low memory". I couldn't find a value where the system boots normally to reproduce the aic7xxx kernel bug. Could it be the reason that the system has only 512MB RAM? If it solves the problem I can maybe convince my boss to invest in some more RAM. However I would prefer another solution...
