SubjectRe: Something broken in sys_swapon
Hmm...Guessing that it had something to do with set_blocksize, I added
this patch to the kernel:

--- linux/fs/block_dev.c.orig Sun Nov 4 11:35:05 2001
+++ linux/fs/block_dev.c Sun Nov 4 11:54:39 2001

/* Ok, we're actually changing the blocksize.. */
bdev = bdget(dev);
sync_buffers(dev, 2);
+ printk("Changing device %02x:%02x block size from %u to %u\n",
+ MAJOR(dev),MINOR(dev),
+ blksize_size[MAJOR(dev)][MINOR(dev)],size);
blksize_size[MAJOR(dev)][MINOR(dev)] = size;
bdev->bd_inode->i_blkbits = blksize_bits(size);
kill_bdev(bdev);
And tried booting again with /dev/hdb2 swap in my fstab...

NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
Changing device 03:02 block size from 1024 to 2048
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 224k freed
Changing device 03:03 block size from 1024 to 4096
Adding Swap: 265064k swap-space (priority 0)
Changing device 03:42 block size from 10739452 to 4096

attempt to access beyond end of device
03:02: rw=0, want=10555926, limit=4096

It looks like it's not changing 03:02 (/dev/hda2, my root fs), which is
good, but it seems to be trying to change 03:42 (/dev/hdb2) even though
that device doesn't exist (which could also be fine, but it looks like it
wasn't initialized). I'm guessing blksize_size is statically allocated,
so this isn't a problem.

I wonder what else could cause 03:02 to barf... Hmm.
