RE: Kernel Problems with System.map
I will answer my own question incase anyone else is experiencing the
same problem. It seems to occur when you link in any filesystem driver
as a module. I have recompiled the kernel about 20 odd times in the
last 2 weeks without the problem going away, but after I decided to not
link in smbfs as a module and compile it directly into the kernel the
problem disappeared.
Is anyone aware of this being a logged problem?

Subject: Kernel Problems with System.map
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:
