The latest released kernel hangs on boot when the pc doesn't have a
keyboard attached, previous kernel boots ok.
Version-Release number of selected component (if applicable):

Actual Results: Upgraded to the latest kernel
Expected Results: Boot without problems
Pentium III 1GHz
kernel-2.4.7-10 boots fine.
Repeatable on systems with USB keyboards
Seems to be APM related. Appending "apm=off" to the boot prompt allows system to
boot. Lockups happen right after "mxt_scan_bios: enter".
Occurs in the 7.3 (2.4.18-3,4) kernels also.
Occurs on various P-III motherboards (Intel & Tyan).
Also occurs on various kernels, including stock kernels
Solved in 2.4.18-14 from RH 8.0
PS: And no problem with 2.4.7-10
from RH 7.2
But the "apm=off" helps! thanks!
Since my last message, a new ERRATA Kernel is available.
2.4.18-17.7.x for solves the problem under RH 7.2 and 7.3
