Bug#890039: linux-image-4.14.0-3-amd64: unable to handle kernel NULL pointer dereference
I'm experiencing the same bug. When updating the system, the computer becomes
unresponsive and after a hard reboot I see a kernel error in the log
(BUG: unable to handle kernel NULL pointer dereference at
00000000000000b0, IP: pids_free+0x11/0x40).
I'm using linux-image-4.14.0-3-amd64 (4.14.13-1) and after downgrading
to a self-compiled kernel (version 4.13.16) I don't see this problem any
longer.
Cheers,
Thomas
