Hello, this is my first post here, and I'd like to report the bug is also affecting me. I have been using Debian unstable (AMD64) for about two years (with regular updates every several days), and the issue started to occur around the beginning of August (never had this problem before). My first thought was it was my hardware malfunction, but fortunately I've found this topic, so hopefully it's not my machine :)
My hardware is Intel Core Duo, Gigabyte GA-EP45T-UD3R; I have tried different kernels (distribution provided, and my own), but no difference. The problems has statistically occured once per a few reboots. But near a week ago I downgraded e2fslibs and e2fsprogs to the following versions: e2fslibs_1.41.3-1_amd64.deb e2fsprogs_1.41.3-1_amd64.deb and have not had this issue since then. I know it may be only a coincidence and "a false positive", but maybe it could be worth a try... And maybe a clue (hopefully not a confusion). (of course I'll let you all know if this happens to me again using those downgraded libs). I hope this issue will be fixed soon. Good luck and keep the great work going on! B. Regards, Tomasz Grzelak
