https://bugzilla.kernel.org/show_bug.cgi?id=208891 --- Comment #31 from Matt Turner (mattst88@xxxxxxxxx) --- Unexpectedly, hotplug worked a few times. I've attached dmesg and sudo lspci -vv output from two hotplug attempts with v5.8.3, CONFIG_PCI_DEBUG=y, initcall_debug, and the patch from comment #24 applied -- one that succeeded and one that failed. Again we see the same pattern in lspci -vv output: --- lspci-patched-failure 2020-08-27 12:54:22.300504263 -0700 +++ lspci-patched-success 2020-08-27 12:47:04.525430133 -0700 @@ -654,9 +654,9 @@ Latency: 0 Interrupt: pin A routed to IRQ 167 Bus: primary=2d, secondary=2e, subordinate=2e, sec-latency=0 - I/O behind bridge: 00000000-00000fff [size=4K] - Memory behind bridge: 00000000-000fffff [size=1M] - Prefetchable memory behind bridge: 0000000000000000-00000000000fffff [size=1M] + I/O behind bridge: 00005000-00005fff [size=4K] + Memory behind bridge: 68000000-680fffff [size=1M] + Prefetchable memory behind bridge: 0000006000000000-00000060000fffff [size=1M] Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- <SERR- <PERR- BridgeCtl: Parity- SERR+ NoISA- VGA- VGA16- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- -- You are receiving this mail because: You are watching the assignee of the bug.
