Pali, et al, I'm encountering a problem booting an i.MX6-based device (Gateworks Ventana SBC). This is apparently a known issue: https://lkml.org/lkml/2020/7/16/388 Do you guys know of a fix for this? Booting this machine reliably is lately impossible. First, it spews a warning: pcieport 0000:00:00.0: PME: Signaling with IRQ 310 sysfs: cannot create duplicate filename '/devices/platform/soc/1ffc000.pcie/pci0000:00/0000:00:00.0/0000:e0' CPU: 2 PID: 7 Comm: kworker/u8:0 Not tainted 5.14.0-rc3+ #40 Hardware name: Freescale i.MX6 Quad/DualLite (Device Tree) Workqueue: events_unbound async_run_entry_fn unwind_backtrace from show_stack+0x10/0x14 show_stack from dump_stack_lvl+0x40/0x4c dump_stack_lvl from sysfs_warn_dup+0x54/0x60 sysfs_warn_dup from sysfs_add_file_mode_ns+0x154/0x1a8 sysfs_add_file_mode_ns from sysfs_create_bin_file+0x60/0x8c sysfs_create_bin_file from pci_create_resource_files+0xf4/0x140 pci_create_resource_files from pci_bus_add_device+0x20/0x8c pci_bus_add_device from pci_bus_add_devices+0x3c/0x80 pci_bus_add_devices from pci_bus_add_devices+0x70/0x80 pci_bus_add_devices from pci_host_probe+0x3c/0x90 pci_host_probe from dw_pcie_host_init+0x200/0x4b4 dw_pcie_host_init from imx6_pcie_probe+0x338/0x668 imx6_pcie_probe from platform_probe+0x80/0xc0 platform_probe from really_probe+0x158/0x324 really_probe from __driver_probe_device+0x84/0xe4 __driver_probe_device from driver_probe_device+0x34/0xd0 driver_probe_device from __driver_attach_async_helper+0x20/0x38 __driver_attach_async_helper from async_run_entry_fn+0x24/0xb4 async_run_entry_fn from process_one_work+0x164/0x3b0 process_one_work from worker_thread+0x2c/0x52c worker_thread from kthread+0x110/0x154 kthread from ret_from_fork+0x14/0x24 pcieport 0000:01:00.0: enabling device (0140 -> 0143) Then: Unable to handle kernel paging request at virtual address 6f736572 (ASCII = "reso") pgd = (ptrval) [6f736572] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Modules linked in: CPU: 2 PID: 7 Comm: kworker/u8:0 Not tainted 5.14.0-rc3+ #40 Hardware name: Freescale i.MX6 Quad/DualLite (Device Tree) Workqueue: events_unbound async_run_entry_fn PC is at string_nocheck+0x20/0xa0 LR is at string+0x54/0x64 Process kworker/u8:0 (pid: 7, stack limit = 0x(ptrval)) string_nocheck from string+0x54/0x64 string from vsnprintf+0x1c4/0x48c vsnprintf from vprintk_store+0x80/0x33c vprintk_store from vprintk_emit+0x6c/0x1e0 vprintk_emit from vprintk_default+0x20/0x28 vprintk_default from printk+0x1c/0x2c printk from sysfs_warn_dup+0x50/0x60 sysfs_warn_dup from sysfs_add_file_mode_ns+0x154/0x1a8 sysfs_add_file_mode_ns from sysfs_create_bin_file+0x60/0x8c sysfs_create_bin_file from pci_create_resource_files+0xf4/0x140 pci_create_resource_files from pci_bus_add_device+0x20/0x8c pci_bus_add_device from pci_bus_add_devices+0x3c/0x80 pci_bus_add_devices from pci_bus_add_devices+0x70/0x80 pci_bus_add_devices from pci_host_probe+0x3c/0x90 pci_host_probe from dw_pcie_host_init+0x200/0x4b4 dw_pcie_host_init from imx6_pcie_probe+0x338/0x668 imx6_pcie_probe from platform_probe+0x80/0xc0 platform_probe from really_probe+0x158/0x324 really_probe from __driver_probe_device+0x84/0xe4 __driver_probe_device from driver_probe_device+0x34/0xd0 driver_probe_device from __driver_attach_async_helper+0x20/0x38 __driver_attach_async_helper from async_run_entry_fn+0x24/0xb4 async_run_entry_fn from process_one_work+0x164/0x3b0 process_one_work from worker_thread+0x2c/0x52c worker_thread from kthread+0x110/0x154 kthread from ret_from_fork+0x14/0x24 Code: e1dd42b2 e58d301c e3540000 0a000019 (e5d2e000) -- Krzysztof "Chris" Hałasa Sieć Badawcza Łukasiewicz Przemysłowy Instytut Automatyki i Pomiarów PIAP Al.
