Kernel 2.4.21-pre4 told me it has a bug in buffer.c:2513. The relevant lines of fs/buffer.c are
2512: if (size < 512 || size > PAGE_SIZE) 2513: BUG();
I'm running kernel 2.4.21-pre4 compiled for i386 on a natsemi geode gx1 with ns cs5530a (Acrosser AR-B1565, http://www.acrosser.com/products/ar-b1565.htm). I was running rsync at the time of the bug message. Below is the bug message:

If anyone is interested, I can provide details about my kernel config and run experiments. I'd like to be a proper kernel-hacker, figure this out myself, and be generally cool; however, I need to finish my degree before my advisor notices I'm posting on lkml.
