Exactly. The mkext2.py script helped to pinpoint it because it creates a filesystem with a low number of blocks per group (1024), it's a bit uncommon but it's a legal value anyway. ext2 and ext3 are not affected by this bug. Curiously, the bug went unnoticed for a long time, it is present since the 2.6.x serie. This means that anyone with a pendrive formatted with the parameter "-g 1024" can bring a linux system on its knees. :-D -- -------------------- Maurizio Lombardi _______________________________________________ HelenOS-devel mailing list [email protected] http://lists.modry.cz/listinfo/helenos-devel
