I'm transfering a gentoo user report of reiser4 problems: Quote: For me it only panicks when intensive operations are performed on loop file (portage sync, unmount). Main partition is R4CC with default settings with two loop files (portage and ccache) on it. Both are R4CC formatted as well. The first one (portage) is created as sparse file, second one (ccache) is ordinary prealocated loop file. Kernel panic occurs when I sync/unmount portage loop file. Only messages I got are: reiser4 panicked cowardly: reiser4[pdflush(212)]: reiser4_handle_error (fs/reiser4/vfs_ops.c:232)[foobar-42]: Kernel panic - not syncing: reiser4_handle_error (fs/reiser4/vfs_ops.c:232)[foobar-42]: I'd like to point out that this setup worked for few days without problems, but later, probably when sparse file started to grow, it started panicking. /Quote More pointers: http://forums.gentoo.org/viewtopic-p-5112215.html#5112215 I hope this is useful to you Dushan -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
