System configuration: Kernel 2.4.21-32.0.1.ELsmp as downloaded from RHEL vs 3 update 5 I2C 2.9.1 Problems happen in i686 and athlon architectures. Opteron (x86_64)is ok. Compiles are clean on all. When I do modprobe i2c-proc, the following happens: /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol create_proc_entry_R0be93f3a /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol kmalloc_R93d4cfe6 /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol __generic_copy_to_user_Rd523fdd3 /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol remove_proc_entry_Re94539f7 /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol proc_bus_Rd6eafc0f /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol sprintf_R1d26aa98 /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol kfree_R037a0cba /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: unresolved symbol printk_R1b7d4074 /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: insmod /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o failed /lib/modules/2.4.21-32.0.1.ELsmp/kernel/drivers/i2c/i2c-core.o: insmod i2c-procfailed Any idea what might be wrong? Some wrong header getting into the compile somewhere? Other? As I say, x86_64 version is OK. Steve Timm -- ------------------------------------------------------------------ Steven C.
