Description Ulrich Drepper 2008-03-13 12:48:48 EDT
Description of problem:
When removing the MMC while the system is running (this is an X61 with
integrated MMC reader) the system hangs.  In the logs it shows

  protection fault: 0000 [1] SMP DEBUG_PAGEALLOC

I cannot see more information, even if it's printed on the console, because the
kernel doesn't restore the backlight on this machine.  So I cannot switch to the
text console before removing the card

Version-Release number of selected component (if applicable):

and earlier kernels

How reproducible:

Steps to Reproduce:
1.insert and mount MMC
2.remove MMC
Actual results:
system completely freezes

Expected results:
no freeze

I haven't seen this for quite a while.  Current F9 kernels work.  Closing.
