It can be found in my tree in the fix_ring_expansion branch: git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git=20 https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=3Dfi= x_ring_expansion The larger rework of ring expansion is also done, but not very well tested. If you can try it out as well it would be appreciated. It can be found in the same tree in the rework_ring_expansion branch https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=3Dre= work_ring_expansion In fear of regression I think I'll submit the smaller fix to 6.4 and older stable kernels, and then rebase the larger rework on top of that, and submi= t it to usb-next. (6.5 kernels and later) --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
