+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
