ow, ugly.

Please try removing the special kernel boot options.  If any of them are
still needed in 2.6.23/2.6.24 then please raise separate bug reports
for that.

I suspect that the only practical way in which we'll be fixing this is if
you can run a bisection search to find the offending commit.

Thank you for the prompt response.

By removing the reserve=0x1000,0x0fff from kernel options initramfs issue is resolved. I had to recently add reserve line in my kernel environment to resolve a reboot issue ( reboot was acting like shutdown) on compaq 6910 mobile machine. 

I will test the compaq 6910 to see if the reboot issue is resolved in 2.6.23 or 2.6.24. I have already tested 2.6.22.5 and the issue of reboot still exist on compaq 6910.
