Actually this appears to be the bug that Jens fixed with this patch, and with that patch my system seems fine as well: diff --git a/block/as-iosched.c b/block/as-iosched.c index b201d16..9603684 100644 --- a/block/as-iosched.c +++ b/block/as-iosched.c @@ -1275,9 +1275,13 @@ static void as_merged_r

task blocked in sync_buffer from ext3_free_branches

I'm getting the following while building a kernel (with make -j24 on an 8 CPU system: 4 socket dual-core opteron) with current Linus git (5b10ca19 is my head). Once this happens the build is hung, although I can ssh in and get a new shell OK. Any ideas or suggestions on what would be useful debug
