Hello,
I noticed that the amount of memory used by the Linux kernel steadily
increases over time on SMP systems (x86 architecture, 32-bit kernel).
This problem disappears when I add maxcpus=1 to the kernel command
line. I have observed this behavior both on the 2.6.22.18 and 2.6.24.2
kernels. Did anyone notice anything similar ?

Thanks for the hint. If I interpreted the 2.6.24 changelog correctly
this patch is already included with 2.6.24 ? The problem still occurs
with 2.6.24.2. I am currently trying to find the minimal kernel config
which still triggers this problem. Any other hints for finding the
cause of this issue are welcome of course.
