Exactly. I have the same printk with a Panasonic DVD-RAM. The line
probably causing it is in scsicam_bios_param(), which is called by the
ioctl:

if (!(bh = bread(MKDEV(MAJOR(dev), MINOR(dev)&~0xf), 0, 1024)))
return -1;

Anyway, if I use the '-b 2048' option for both fdisk and mke2fs,
everything seems to work. It's just an annoying printk.

BTW, shouldn't be fdisk and mke2fs be smart enough to realize that we have
2kB blocks? AFAIK the SCSI devices _do_ report this.
