Comment 1 Dave Jones 2006-03-06 17:55:46 UTC

This rings a bell, I think this got fixed upstream.
Can you grab the latest boot.iso's and test ?

Comment 3 Orion Poplawski 2006-03-06 23:10:37 UTC

Still seen with today's (2.6.15-1.2009.4.2_FC5)

Comment 4 Dave Jones 2006-03-06 23:34:41 UTC

argh, latest kernel from people.redhat.com/davej/kernels/Fedora/devel hasn't
been moved into rawhide for a few days, so the boot.iso hasn't been updated. 
I'll make sure tomorrows gets updated.

Comment 5 Orion Poplawski 2006-03-07 16:42:32 UTC

Still present with 2.6.15-1.2025_FC5

Comment 6 David Woodhouse 2006-03-10 12:20:43 UTC

was fixed upstream yesterday.

Comment 7 Orion Poplawski 2006-03-14 22:36:04 UTC

Confirmed gone.
