Hello

I have a new problem when I remove my usb pen. If in X, everything
freezes; if not, it goes into db>. The error message before that is:

[by hand]
uvm_fault (0xc06c7900, 0x500f000, 1) -> 0xe
kernel: supervisor trap page fault code=0
stopped in pid 4.1 (usb0) at netbsd:kprintf + 0x8d2: repne scasb (%esi)

I can do a bt, s, etc., in db but I don't know how to save the output.

TIA for your help. I attach the dmesg (+ 1/2 dmesg which shows a
different usb pen attached at boot).
