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:
