No.  The kernel may signal EIO to any subsequent operation.  In addition
even such aggressive action is not required, let alone a panic:  UFS does 
not behave this way.  Accesses to uncorrupted sections of a drive usually 
proceed normally.

Please be careful with statements such as "the only way"--especially when
the way you describe is demonstrably bad.
