If it doesn't work, let me know (and tell me how you are booting it). On my 6400, it compiles and boots OK, but there are some little itches: - rsync complains about "send_files failed to open Documentation/kernel-docs.txt: Permission denied" - rsync copies a spurious file drivers/net/.#ppp_generic.c which is a dead symlink - during booting, there is a message "/proc/sys/net/ipv4/ip_always_defrag is missing - Cannot control IP fragmentation" - while using my ethernet card with the de4x5 driver, I get hundreds of "kernel: Warning: kfree_skb on hard IRQ c010ded8". Seeing that this address is inside the de4x5 driver, I tried to compile it as a module, so that I could also compare it to the tulip driver. Didn't work at first: - the tulip module loads without problem, but doesn't seem to like my ethernet card (DEC 21041 chip). It gives me hundreds of "kernel: eth0: 21041 transmit timed out, status fc6800". With 2.2.14 kernels, the tulip module works OK. - the de4x5 module complains about missing symbols; and this is in fact a bug I had mentioned already some days ago. I repeat the patch below. It seems to be necessary, and it cures the problem. I am now on the net with de4x5 as a module, but I still get the warnings, now with an address in the module: Feb 13 15:06:14 rennes-231 kernel: Warning: kfree_skb on hard IRQ c7159770 Feb 13 15:07:24 rennes-231 last message repeated 421 times Feb 13 15:12:01 rennes-231 last message repeated 97 times and so on. How can I get rid of the warnings (short of disabling the line that produces it in net/core/skbuff.c)? Here is the patch needed by pci driver modules: --- arch/ppc/kernel/ppc_ksyms.c.ori Fri Feb 4 10:18:20 2000 +++ arch/ppc/kernel/ppc_ksyms.c Fri Feb 4 10:28:10 2000 @@ -11,6 +11,7 @@ #include #include #include +#include #include #include @@ -137,6 +138,9 @@ EXPORT_SYMBOL(__clear_user); EXPORT_SYMBOL(__strncpy_from_user); EXPORT_SYMBOL(__strnlen_user); + +EXPORT_SYMBOL(pci_alloc_consistent); +EXPORT_SYMBOL(pci_free_consistent); /* EXPORT_SYMBOL(inb); -- Martin ** Sent via the linuxppc-dev mail list.
