Subject: kernel BUG in new r8188eu
Date: Fri, 30 Jul 2021 14:59:44 -0500 [thread overview]
Message-ID: <80042e9f-6811-38f3-010b-1c0951ba88db@lwfinger.net> (raw)
Greg,
When I unplug the USB device with the driver loaded, I get the following BUG and
my laptop freezes:
kernel: BUG: unable to handle page fault for address: ffffeb0200043248
kernel: #PF: supervisor read access in kernel mode
kernel: #PF: error_code(0x0000) - not-present page
The traceback points to a kfree() call. I do not understand this BUG. Can you
explain what happens?
I think I know how to avoid the BUG, but that might be at the expense of a
memory leak.
Thanks,
Larry
