Hi, the commit below causes infinite interrupts to be generated on some chips. Namely on IBM x3850 M2. commit 235dae5d094c415fcf0fc79fa637f1901bc8afe2 Author: Philippe Langlais <philippe.langlais@xxxxxxxxxxxxxx> Date: Thu Jul 29 17:13:57 2010 +0200 U6715 16550A serial driver support The culprit is the added size_fifo call proper in autoconfig_16550a. It returns 16, but the chip is confused by what the function does at that point. It is yet to be investigated why. Any ideas at this stage why this could be a problem? thanks, -- js suse labs -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
