I think I posted a link to that same bug report. The problem is that if the BIOS wasn't allocating it before, it isn't allocating it now, because it's still the same A11 bios that Dell shipped it with. And now I'm not sure which is more confusing - that it was OK in -0703 and borked in -0709, or that between two successive boots of the same -0709 kernel it cleared itself up.... --==_Exmh_1374012998_1500P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iQIVAwUBUeXGRgdmEQWDXROgAQK46xAAq6UWeBif7iqGImx5cihgT51RCoh9K8UO u25hbQt4UHMkUudoOEvBufP0Q/YE4I+lumgci0DtfxuVAUCPrzPUGGrcoqk0J2c6 F5+paQq0EyVdJloC8GrooXK96kBMoH/u/Q76qowGhvivscsWxHtU2sA+5EKOGZsx yks8qbEK7Wi0erjfGPzS9WwJynaAYtfNqZW70AUlJp608/60PLsPFLLmsk0hZTDn cYkNfycxxILO07wzb8ZZXgqylfmBh94ill5GEXC2u9u+IVRNitQsEHAqAPfKYMbA VgLmSCY66eMufKhG/P5PeeR8pgX9qGLW8WlkHroU5Tk4H7Pq4WRUCugAPKlwCHBz tcqQ9i2ZxmYxQr65spYKYm0dCYRUVeo9c4sozJNp4eRkSoiIleZHhyxqmuGDlWFc JQ7LmGYlVeOXwWUp2INgjVPL/4N+kk+uvHMAggJpLvC0rYaZ7FgHKqOscIlyNwL9 fosCoQxyuzR03tlzqdWCB+eLs5mFjmNvfiXFbJoX/CI9lJFr+uryvL5oi109o2/I U3KunvrmbwZoqu4M1EiOxaNuAdh7KFPm0tEq7+ZhVz1mfX5p9qUV5EZNNJM2mPAd YTjWXHMBzmCJhngIYnWgjJgU5ClXwwzK93HZnkvnJseM1Hyi5N3d7U4kUPDWyvUu SquLYjyZ0fM= =B12+ -----END PGP SIGNATURE----- --==_Exmh_1374012998_1500P--
