Description (last modified by )
When I remove an usb stick without unmounting it first (I know it's rude) Haiku crashes with the message:
PANIC: vm_page_fault:unhandled page fault in kernel space at 0x8382228c, ip 0x8382228c Welcome to Kernel Debugging land... Thread 282 "device event" running on CPU 0.
This happens on both my haiku laptops with several sticks.
It seems that this causes an unhandled exception.
Note:
See TracTickets
for help on using tickets.
Unplugging a mounted USB stick getting you to KDL is not too unexpected, although it shouldn't actually crash, but panic stating that something couldn't be written back (i.e. indicating data loss). If you can still reproduce this unhandled page fault, then please run the "bt" command in KDL and attach the output here.
