does not match kernel data

["Lito A. Lampitoc" <ral@codewan.com.ph>]

Hi All,

after upgrading from kernel-2.2.20 to 2.2.22, using make-kpkg I got the
following error while doing ps:

{iommu_get_scsi_one_gflush} {___f_mmu_get_scsi_one}
Warning: /boot/System.map-2.2.22 does not match kernel data.

I copied System.map-2.2.22 to / as per advised from the web, but doesnt
work. What do you think is the problem here. Is this a serious error?
Hope you could help me here.

Thanks.
