Dear kernel maintainers,
I will report my problem around 2.4.0-test kernel.
Thanks in advance.
--- [1.] failed in BUG() at fs/buffer.c:765 [2.] My linux 2.4.0-test12 box failed on writing some files on soft-raid partition. It seems to touch BUG() macro at fs/buffer.c:765, when file buffer exceeds a certain amount!? The raid partion is build under earlier 2.4.0-test* kernel, and relatively stable on at least 2.4.0-test10.[3.] kernel BUG, buffer.c, raid5d [4.] Linux version 2.4.0-test12 (root@cuvier) (gcc version 2.95.2 20000220 (Debian GNU/Linux)) #1 SMP Wed Dec 13 10:18:18 JST 2000
