It fails if we attempt to read beyond the bound. Impact: Several errors will be logged if, for example, zram-config is installed: [ 14.666280] zram: module is from the staging directory, the quality is unknown, you have been warned. [ 14.667040] zram: Creating 1 devices ... [ 14.830355] Buffer I/O error on device zram0, logical block 62411 [ 14.830375] Buffer I/O error on device zram0, logical block 62411 [ 14.830598] Buffer I/O error on device zram0, logical block 62411 [ 14.830621] Buffer I/O error on device zram0, logical block 62411 [ 14.878597] Adding 249644k swap on /dev/zram0. Priority:5 extents:1 across:249644k SS Fix: Commit 75c7caf5a052ffd8db3312fa7864ee2d142890c4 "zram: allow request end to coincide with disksize" fixes the issue by correcting the test in valid_io_request() function. Testcase: I was able to reproduce the issue by simply installing zram-config in a precise box. ========================================================================================= This is a duplicate of #1217189, but for some reason neither @oibaf nor me can reopen it. It is in "fix released" state, but the problem is at most partially solved. It seems that the bug no longer causes lockups (described in another bug: #1215513), but is still present (as I get error messages on boot screen and after $ dmesg | grep zram). If someone has enough privileges to reopen 1217189 for "linux (ubuntu)" (I don't know about raring, but no one complains, so it is probably ok), and remove this bug (maybe merging this message to the comments in 1217189), I would be really grateful. Ubuntu 12.04.3 LTS Kernel Linux 3.2.0-56-generic-pae (the problem was first observed in 53 and since 54 there are no lockups). --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
