Bug#508834: grub-probe is painfully slow to execute due to excessive ioctl(BLKFLSBUF)

[Jason White]

Package: grub-common
Version: 1.97~beta3-1
Severity: normal


I only have one partition, a Linux partition with an XFS file system.
nevertheless, grub-probe takes several minutes to complete and takes the load
average up to 11 on my quad-core machine.

I suspect I am experiencing a manifestation of this bug. Its priority should
not be wishlist; it's a normal bug.
