-Hi,
-a while back I sent a few mails regarding spurious interrupts in the
-UARTA (hsuart) block of the Tegra2 SoC, when using the 8250 driver for
-it instead of the hsuart driver. After going down a pretty deep
-debugging/testing hole, I think I found a patch that fixes the issue. So
-far testing in a reboot-cycle suggests that the error frequency dropped
-from >3% of all reboots to at least <0.05% of all reboots. Tests
-continue to run over the weekend.
-
-The patch below already is a second iteration; the first did not reset
-the MCR or contain the lines below '// clear interrupts'. This resulted
-in no more spurious interrupts, but in a few % of spurious interrupts
-that were recovered the UART block did not receive any characters any
-more. So further resetting was required to fully reacquire operational
-state of the UART block.
-
-I'd love any comments/suggestions on this!
-
-Cheers,
-
-David
