[Bug 1165535] System lockup under memory pressure using encrypted swap on SSD (failed command: WRITE FPDMA QUEUED)
https://bugzilla.suse.com/show_bug.cgi?id=1165535 https://bugzilla.suse.com/show_bug.cgi?id=1165535#c5 Hannes Reinecke <hare@suse.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sebastian.chlad@suse.com Flags| |needinfo?(sebastian.chlad@s | |use.com) --- Comment #5 from Hannes Reinecke <hare@suse.com> --- I wouldn't discount the possibility that we're not properly for memory allocation problems, or that the code paths catching these issues are improperly done. IE if there's a memory allocation error (in, say, dm-crypt), and dm-crypt improperly handles the failed allocation in that it catches -ENOMEM yet continues with operation we might end up with such a situation. But as you figured, triggering this is extremely hard. But maybe worthwhile a testcase, and maybe our eager QA team can spin off something here. Sebastian? Do you think it would be possible to devise a testcase for testing this situation? -- You are receiving this mail because: You are on the CC list for the bug.
