Naaa, its old modutils. Upgrade to 2.3.21 and this problem will disappear. (explaination: with old modutils, the kernel "forgets" to copy some bytes into module space, which causes these zero'd bytes. modutils 2.3.21 fixes this. In addition, the kernel bug has also been fixed in the current pre patches, but this is not a recommendation to try the pre kernels out). _____ |_____| ------------------------------------------------- ---+---+- | | Russell King rmk@arm.linux.org.uk --- --- | | | | http://www.arm.linux.org.uk/personal/aboutme.html / / | | +-+-+ --- -+- / | THE developer of ARM Linux |+| /|\ / | | | --- | +-+-+ ------------------------------------------------- /\\\ | - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
