It's not an UART problem but a system performance issue, which is caused by the fact that SD driver lacks of card detection support. The card present polling in SDHCI based driver is very expense, and impacts system performance a lot. Adding card detection support solves the problem. The patch set targeting mainline was submitted as below.
http://thread.gmane.org/gmane.linux.kernel.mmc/8495 But it does not apply against Linaro kernel tree, neither .38 nor .39. I will probably submit a quick fix against Nicolas' .39 tree. Let me know if anyone has different opinion. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/754254 Title: imx51 randomly truncates serial input at 31 characters To manage notifications about this bug go to: https://bugs.launchpad.net/linux-linaro/+bug/754254/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
