Same thing since I upgraded to 4.15.0-151-generic on my laptop.
Previously had 150+ days of uptime, now it crashes every few days, and
up to 3 times a day.
Very similar behaviour than what Martin reported just above: when
logging in to XFCE, it can crash easily, or when simply using the
Desktop.
I have a similar behaviour (hangs) recently, once with a corrupted
filesystem, had to force shutdown laptop several times a day. Today when
I was in console and not GUI (because the hang happened already during
logging in to Xfce and I was lucky to be able to switch via Ctrl-Alt-F1
to console, I
For Nick White: would you be able to supply the output you saw when your system
hung (if this is already past mounting the real rootfs there could be old
entries. journalctl --list-boots to see which and journalctl -b to show
logs from a previous boot).
Unfortunately we cannot see any hangs

I think all data is a little inconclusive. There are things across many
places which seem to go wrong in seemingly random patterns. Which makes
me a little suspicious about locking (alternatively maybe memory
management). Looking over the changes there was mutex change which seems
subtly different
My stacks are inconclusive I would think. Sometimes there was a hang
without a stack. Some examples asre

Though it doesn't sound exactly like the issue that @Juerg Haefliger
originally describes, I've had the same issue as @Jan (above) on 3
separate laptops (all Lenovo T480s machines). In each case, the upgrade
to 4.15.0-151 caused file system corruption that could only be corrected
by a manual
I've also had issues with this kernel on two machines. On my Thinkpad T460p
(Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz), I had two cases where the ext4
driver suddenly detected an error in the journal and aborted it. Unfortunately,
the system mounted the whole file system read only, so it

I am also having issues since last week when kernel 4.15.0-151 got
installed. I am now using 4.15-0-147 but not long enough to tell if this
changes the picture.
What it does help for is that switching from the GUI to a virtual
console back and forth is now working - again, with 151 it triggered a
