Kernel Problems with System.map

["Chris Mason" <chris@bash.sh>]

Hi,

I have been running 2.2.20 on Debian Sparc (Potatoe) for the past 4
weeks without a problem.  I moved to 2.2.20 from 2.2.19 because I had
this same problem.  I compiled the kernel and installed it as follows:

make menuconfig && make dep && make vmlinux && make modules && make
modules_install
cp /usr/src/linux/System.map /boot/System.map-2.2.20
cp /usr/src/linux/vmlinux /boot/vmlinuz-2.2.20

I have now done this 15 times in succession with the same result.  I
have even unpacked the source from the tar again and re-entered my
configuration as opposed to loading a saved one.  The machine will boot
the new kernel fine without any problems until I issue a ps or a top.

I know for a fact my System.map is the correct one, but I still get
errors about it not matching kernel data.  When I had this error on
2.2.19 it was moaning about a different exported symbol.  Under 2.2.20
it seems to be consistent with iommu_release_scsi_one.  This doesn't
seem to be causing problems to the system, but as you can imagine is
highly irritating.

I have also included the output from ver_linux:
