Hi,
i've noticed that usb on mt7988 is broken in 6.10, was working on 6.9 (with some additional patches like
for pinctrl and dts as this chipset is not completely supported by mainline yet).
i see this in my dmesg

[ 45.364918] xhci-mtk 11200000.usb: HC died; cleaning up
maybe anybody can point me to possible rootcause? as this seem to happen somewhere in interrupt-handling i have no idea where to search
this is what i did till now:
# cat /proc/interrupts| grep xhci
104: 0 0 0 0 GICv3 205 Level xhci-hcd:usb1
105: 100201 0 0 0 GICv3 204 Level xhci-hcd:usb3
mtk xhci driver itself seems unchanged so far

017dbfc05c31 2024-01-04 usb: xhci-mtk: fix a short packet issue of gen1 isoc-in transfer Chunfeng Yun
clocks seems also not the cause

also when trying to find any error like pinctrl or similar seems not showing any more like above related to usb

because of the pcie interrupt messages i checked my nvme and wifi-card and look sgood, so it seems no generic interrupt issue
