There are only two recent revisions to 8250.c. One adds slightly buggy Xscale UART detection, the other fixes the buggyness. What I don't know is whether either of these two changes are the cause of your exact problems, because I don't actually know what you're testing. Since Stephen's bug is a lot more well defined than yours, it makes sense to tackle Stephen's situation first. The reason for this is taht pppd getting a SIGHUP doesn't actually tell me anything at all. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - 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/
