Hence why I said I/O errors on *write*. If the block dev layer reports an error to the VM on page-out, it knows the data hasn't been correctly written. I'm not sure zram actually allocates the whole amount of memory it's configured to use, initially: steved@xubuntu:~$ free total

Been a long time since I looked at the relevant bits of the kernel source, but errors when _writing_ to swap devices should be quite manageble, I would have thought - simply mark the block/page as bad and go looking for another free location. It'll be _read_ errors that cause problems! Some info h

IMO, this bug *is* a duplicate of #1215513. The real problem is that the zram kernel module creates a block device with a bad sector at the end.

A simple workaround is to blacklist the zram module, and update your initramfs: 1. create a text file /etc/modprobe.d/blacklist-zram.conf: blacklist zram 2. enter command update-initramfs -c -k all After reboot, the zram module will not be loaded anymore. You can also temporarily unload the mod

Like Hans, I'm seeing this on 12.04 LTS. linux-image-3.2.0-53-generic- pae seems to enable zram by default, which results in lots of "scheduling while atomic" errors in syslog and occasional lockups (machine still responds to ping, but not ssh, desktop frozen.) This seems like a pretty critical pr
