File system error: Input/output error

[Ben Greear <greearb@candelatech.com>]

I was testing an adaptec 4-port in a RH 7.1 machine running the
2.4.7 kernel.  The Adaptec card caused the system to hang hard, so I
had to power down.  I tried 3 times to get the adaptec to work, locking
the machine hard each time...  But, that isn't the real problem...

Now, when I boot the system, things seem to work, except for one
problem:  I cannot access /etc/modules.conf.  I can't remove, edit,
more, or cat it.  I can't run ls on it...  Every operation complains
of Input/output error, for example:

[root@lf1 /root]# more /etc/modules.conf
/etc/modules.conf: Input/output error


I tried rebooting back to RH's 2.4.3+ kernel, and I get the same
problem.  I tried going to single-user and doing an fsck, but fsck
says everything is fine...

Any ideas before I have to install this thing from scratch?

Thanks,
Ben
