Those keys work nicely normally. But unfortunately they don't work once it freezes with this bug - the freeze is total, which I guess also explains the truncated stack traces. I wasn't suggesting that memory was freed just because the device disappeared - I was wondering if it is possible that the kernel could umount several missing devices and free the memory pertaining to them (all good so far), but get pointers to the freed memory mixed up, possibly through caching of the freed memory pointer. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
