Description Sonal Santan 2006-10-20 12:21:24 UTC

Description of problem:
I see a kernel BUG message when doing suspend/resume on my Dell Latitude D810
laptop. This happens only with kernel 2.6.18-1.2200.fc5. I have been using
kernel 2.6.17-1.2187_FC5 without any such error. Here is what shows up in my dmesg
