Last modified: 2008-08-02 19:40:33 EDT
Description of problem:
Using 64-bit versions, system (HP a1610n - dual AMD 64bit) hangs during boot
load at io scheduler cfg registered (default) with 2.617-1.2187-FC5 64 bit and
FC^ Test 3. Version 2.615-1.2054-FC5 64 bit does not display this problem.
Version-Release number of selected component (if applicable):
32bit versions do not display this problem.
Steps to Reproduce:
1. Install 2054 Core 5 Release
2. Update kernel to 2187
3. Reboot - hang occurs at previously mentioned location

can you boot with the option initcall_debug and see what the last line that
gets dumped says (if different to above?)
If cfq was broken I'd expect a more widespread problem, so it's likely that it's
silently blowing up in whatever gets initialised after cfq.

hanged boot with initcall_debug
Here is a picture from such hang with 2.6.18-1.2239.fc5. A kernel
on an FC6 installer is doing that too. It is actually quite possible
that this is the same as bug 212172 (and maybe a fixed BIOS, if
available, is an answer).
some things to try..
