Hi, i have updated my Sun Ultra 25 to kernel 5.10.0-8.
Somewhere during boot my USB devices get disconnected and no matter how often i unplug and replug them, nothing is shown on dmesg and i am left without working mouse and keyboard. I connect via ssh to the machine and the problem appears to manifest after the lines containing [ 6.360090] ohci-pci 0000:05:1c.0: HC died; cleaning up [ 6.360395] usb 2-1: USB disconnect, device number 2 [ 6.363573] usb 2-2: USB disconnect, device number 3 >From what i have read in some postings on the mailing list, it seems kernel 5.10.0-8 is not working very well for sparc64 anyway. Is there a recommendation for a stable kernel i can use on this machine? dmesg output: [ 4.075142] usb usb3: New USB device found, idVendor=1d6b, idProduct=0001, bcdDevice= 5.10 [ 4.075154] usb usb3: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 4.075160] usb usb3: Product: OHCI PCI host controller [ 4.075165] usb usb3: Manufacturer: Linux 5.10.0-8-sparc64 ohci_hcd [ 4.075169] usb usb3: SerialNumber: 0000:05:1c.1 [ 4.076506] hub 3-0:1.0: USB hub found [ 4.077733] hub 3-0:1.0: 3 ports detected [ 4.081829] ohci-pci 0000:05:1c.2: OHCI PCI host controller [ 4.081852] ohci-pci 0000:05:1c.2: new USB bus registered, assigned bus number 4 [ 4.081947] ohci-pci 0000:05:1c.2: irq 101, io mem 0x7f900204000 [ 4.150372] usb usb4: New USB device found, idVendor=1d6b, idProduct=0001, bcdDevice= 5.10 [ 4.150384] usb usb4: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 4.150390] usb usb4: Product: OHCI PCI host controller [ 4.150395] usb usb4: Manufacturer: Linux 5.10.0-8-sparc64 ohci_hcd [ 4.150400] usb usb4: SerialNumber: 0000:05:1c.2 [ 4.150942] hub 4-0:1.0: USB hub found [ 4.150973] hub 4-0:1.0: 3 ports detected [ 4.173824] ata1.00: ATAPI: TEAC DV-W28SLC, 1.0B, max UDMA/33 [ 4.173842] ata1.00: WARNING: ATAPI DMA disabled for reliability issues.
