Alpha DP264, gcc 3.0.1 compiled.

After some testing and some work, got:

kernel: invalidate: busy buffer

Right after dismounting an ext2 diskette.

Attempting to remount the diskette resulted in:

kernel: kernel BUG at ll_rw_blk.c:660!
kernel: mount(1238): Kernel Bug 1
kernel: pc = [__make_request+2352/2368]  ra = [__make_request+2340/2368]  ps = 0000    Not tainted

Note that I got this once under 2.4.12 also.

I don't have time to run ksymoops right now.

The one from 2.4.12 was:

kernel: kernel BUG at buffer.c:664!
kernel: mdir(27124): Kernel Bug 1
kernel: pc = [invalidate_bdev+448/464]  ra = [invalidate_bdev+436/464]  ps = 0000    Not tainted
