I searched the archives, but was unable to find any information, so
  here it is.
I've now seen two boxes with 2.6.17.7 go down with IO errors after some
  time running.  There doesn't seem to necessarily be a fixed amount of
  time, nor can I precisely figure out what's causing it.
A .config file from one of the affected machines is attached.
  Unfortunately, the syslogs aren't available, since the filesystem got
  mounted readonly right when the problem happened, and I don't see
  anything in the logs that might have caused it, no oops, no nothing.
Any ideas what might be going on?
Thanks!
