your patch works, thanks, but only for the problem with the ignored offset, as expected. Now I can use the original pxafb driver, but with the same problem: All writes from user space in the mmap'ed region after the first 4096 bytes are ignored. Perhaps it is not a kernel bug, but a configuration problem with the platform, because it is a in-house developed platform. Now a colleague is working on this problem and reading a book about the Linux 2.6 kernel details over weekend and learning how to use the kernel debugger (until now we have used printk and flashing new zImages every time, which is very time consuming). I'll post the solution next week, if we'll found one. -- Frank Buß, [EMAIL PROTECTED] http://www.frank-buss.de, http://www.it4-systems.de - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
