Could you put a call to the kernel dump_stack() routine where this
printk is, and send the result? (looks like its a 2.4 kernel? and
if so, looks like the printk is from drivers/md/lvm.c::lvm_map)

This should be easy to fix - looks like we have somewhere that its
somehow possible to issue a write when we're mounted read-only ...
we just need to find the offending piece of code.
cheers.
