Re: Kernel 2.6.25 (F8/F9) problem



Yesterday I installed Fedora Core 9 on three HP DL380 G5's and noticed stability problems from the first boot. Apparently randomly one machine would boot (fairly) normally, the other would freeze during boot and the third would tail out stacktraces (CPU# frozen for 61secs?!). All three were fresh installs from the same DVD on the same hardware. Rebooting the machines was a russian roulette on which would come back up.

I upgraded from 2.6.25-14.fc9.i686 to 2.6.25.6-55.fc9.i686 and still had the same problem on all three machines. Below is a snapshot from dmesg showing the problem. I have just installed 2.6.26-0.98.rc8.git1.fc10.i686 and the problem seems to have gone away.
