Two questions about taint system..
1. I have a installation of archlinux with kernel 3.0, just after boot I cat /proc/sys/kenrel/tainted and receives 1024, but cat /var/log/messages | grep -i taint gives me no output. How can I know what is tainting my kernel?
Look for the "BIOS is broken..." message, 1024 is TAINT_FIRMWARE_WORKAROUND.
2. I was studying char devices, and have writed some code. I have put the MODULE_LICENSE("GPL"); on the module, build it, put it on a initrd image and boot with qemu using -kernel and -initrd options. When I loadit with modprobe I receives a message on console saying that kernel was tainted and /proc/sys/kernel/tainted gives me 4024. There is any other thing on module, besides license that can taint the kernel?
Yes, lots of things, look at kernel.h for the full list. hope this helps, greg k-h
