#18461 new bug
Deskbar can become stuck/unkillable with bad usb

Description
I have a usb thumb drive, plugging this into my xhci port and then hovering over the mount menu will freeze the deskbar menu.
After this happens Deskbar is unkillable, only after I've unplugged the usb thumb drive it will continue with the kill.
hrev56756 (I'll update in a bit and retest also)
I strongly suspect this is deskbar beeing stack in a system call, i don't know which however. the debug report i did manage to capture (after asking it to be killed) is suprisingly empty

Still present after recent USB changes. Also observed on riscv64 VisionFive 2.

The thread waiting for a USB disk lock and the thread actually holding it, I mean.

The recent refactors to the USB disk driver almost certainly make a difference here. So indeed please retest with a recent hrev.
