Bug#812416: drbd module general protection fault while shutting down system with drbd device
Package: linux-image-4.3.0-0.bpo.1-amd64
Version: 4.3.3-5~bpo8+1
Kernel:
# uname -a
Linux bac1f6065n 4.3.0-0.bpo.1-amd64 #1 SMP Debian 4.3.3-5~bpo8+1 (2016-01-07) x86_64 GNU/Linux
Libc6
# dpkg -s libc6 | grep Version
Version: 2.19-18+deb8u1
This issue occasionally happens while shutting down a system with a drbd block device.
I have traced it back to this line in the drbd module:
0x297e8 is in nla_put_status_info (include/linux/list.h:189).
184 * list_empty - tests whether a list is empty
185 * @head: the list to test.
186 */
187 static inline int list_empty(const struct list_head *head)
188 {
189 return head->next == head;
190 }
