Hi! I happened to own one of Exar's PCI serial adapters, and this commit that I bisected breaks suspend/resume of the host. The adapter that I have: 02:00.0 Serial controller [0700]: Exar Corp. XR17V3521 Dual PCIe UART [13a8:0352] (rev 03) (prog-if 02 [16550]) First suspend of the system works,but on the second suspend, the system hangs until it reboots. Reverting the commit helps. I attached a backtrace captured with ramoops (since I ironically use this serial port to capture the oops backtraces otherwise...) Best regards, Maxim Levitsky
