 Use the following procedure for all kernel versions. There are six steps
 numbered one through six. Please do them in order and not skip one.
 

-An important note about the use of modules for PPP:
-
-The module support for the Linux system supports a concept of configuring
-the external names so that they pertain to only a specific version of the
-kernel. This is enabled by answering "y)es" to the configuration question
-of "Set version information on all symbols for modules?".
-
-There is a problem with enabling this and the PPP code under some
-circumstances. It will not work if BOTH of the following is true:
-
-a) You elect to load the PPP driver into the kernel; and
-b) You want version information for all other modules.
-
-The problem is one of the module code itself. It is not able to recognize
-that the symbols loaded into the kernel symbol table may not have been
-defined with the new names for the symbols. The symbols defined by the
-PPP code will not have version information attached to them.
-
-The solution to the problem is simple. Don't do both things at the same
-time. The means that it is valid if you either (a) don't use version
-information; or (b) don't put the PPP code into the kernel (use it as a
-module instead) if you want to use version information.
-
-I will see what I can do to get around this limitation. However, for the
-time being, this is a limitation.

-3. Verify the Makefile in the kernel.
-
-The drivers/net/Makefile in the kernel must have the proper definition
-for the BSD compression module. As of 2.2.0a, the code will only build
-as a module. This means that if you have had an earlier version of the
-PPP logic and this is an update to the kernel then it is possible that
-the patch to the Makefile did not work and you will be left with a
-kernel which will not build correctly.
-
-Please, read carefully the following.
-
-Look that the kernel version which you are building. If the version is
-1.2.x (1.2.0 though 1.2.99999, whatever) then use the set of entries
-for the 1.2 kernel. If the kernel is for 1.3.x and resembles the lines
-in the 1.3 kernel entry then use those. There is a point in the early
-1.3 kernels where the Makefile actually was that of the 1.2 series.
-Please don't just use the 1.3 kernel change unless your makefile
-RESEMBLES the patch indicated.
-
-I don't know how to stress this enough. If you choose the wrong one
-then the makefile will not work. Your kernel build will fail. In that
-case, use the other one. There are only two variations. Please choose
-the proper one. Only one will work.
-
-Check the makefile. If your kernel is 1.2 then it should be similar to
-the following:
-
-ifdef CONFIG_PPP
-NETDRV_OBJS := $(NETDRV_OBJS) ppp.o
-CONFIG_SLHC = CONFIG_SLHC
-else
-MODULES := $(MODULES) ppp.o
-endif
- 
-MODULES := $(MODULES) bsd_comp.o
-
-ifdef CONFIG_SLIP
-NETDRV_OBJS := $(NETDRV_OBJS) slip.o
-CONFIG_SLHC = CONFIG_SLHC
-else
-MODULES := $(MODULES) slip.o
-endif
-
-The critical entry is the line which says "MODULES := $(MODULES) bsd_comp.o"
-and that you don't have "NETDRV_OBJS := $(NETDRV_OBJS) ppp.o bsd_comp.o".
-
-IF YOU HAVE THE 1.3 KERNEL, the following is the expected pattern in the
-Makefile.
-
-ifeq ($(CONFIG_PPP),y)
-L_OBJS += ppp.o
-CONFIG_SLHC_BUILTIN = y
-else
-  CONFIG_SLHC_MODULE = y
-  M_OBJS += ppp.o
-  endif
-endif
- 
-ifneq ($(CONFIG_PPP),n)
-  M_OBJS += bsd_comp.o
-endif
-
-ifeq ($(CONFIG_SLIP),y)
-L_OBJS += slip.o
-CONFIG_SLHC_BUILTIN = y
-else
-  ifeq ($(CONFIG_SLIP),m)

 
 

-Again, ensure that the statement reads "L_OBJS += ppp.o" and not
-"L_OBJS += ppp.o bsd_comp.o".

+BLOCK ON FREELIST AT nnnnnn ISN'T FREE
+(where nnnnnn are a sequence of hexadecimal digits.)
+
+While this is not really an error when the kernel is built, it is an error
+which may occur when you actually run the system. The solution is a patch
+in the linux/Other.Patches directory. (That is why I mention it here.)
+
+The problem is in the VJ header compression module. It allocated a block
+of memory and then used the wrong variable to determine the amount of memory
+which should be reset. The patch is present in the 1.3.46 kernel and later
+ones. However, versions prior to that may POSSIBLY have the problem depending
+upon the number of slots which are allocated for the header compression logic.
