Additional info: Compaq AQ CQ5700Y with original hard drive removed and replaced with a Microcenter brand 64GB SSD. Initially it seemed to work fine under both Fedora 14 and Fedora 15. After upgrading Fedora 15 after install with the latest updates from the repository, this problem manifested. After some repository updates to Fedora 14, the same problem resulted.

Comment 1 Mark Kolesar 2011-07-05 13:42:46 UTC

The last kernel where this bug does not manifest is: 2.6.35.12-90.fc14.x86_64.
Both 2.6.35.13-91.fc14.x86_64 and 2.6.35.13-92.fc14.x86_64 exhibit this problem.

Comment 2 Mark Kolesar 2011-07-08 17:10:02 UTC

Apparently this same bug prevents the practical installation of Fedora 15 on an SSD system. Whereas Fedora 15 Alpha installed without a problem on one of my SSD systems, official release of Fedora 15 hangs during the install. Although it does not come to a complete stop, everything slows down to the point of impracticality.
