We have a number of HP DL385 G2s which kernel panic after installing RHEL 5.3. All are up-to-date with firmware CD 8.50. The initial RHEL 5.3 installation always works and in most cases the first boot is fine (kernel 2.6.18-128.el5); so far 1 in 4 has paniced here. Most of the rest of the machines I've tried fail to boot when "yum update"d to kernel 2.6.18-128.1.10.el5. One or two have been fine.
The panic is always at the same point. The last lines logged on the console are:
device-mapper: uevent: version 1.0.3 device-mapper: ioctl: 4.11.5-ioctl (2007-12-12) initialised: email@example.com usb 4-2: new full speed USB device using uhci_hcd and address 3 device-mapper: dm-raid45: initialized v0.2429 usb 4-2: configuration #1 chosen from 1 choice hub 4-2:1.0: USB hub found hub 4-2:1.0: 7 ports detected
then a pause, then:
kernel panic - not syncing - attempted to kill init
Beyond this point no kernel will boot (including the Anaconda-installed 2.6.18-128.el5) and a reinstall is the only option. It seems very similar to this problem reported on the HP forums.
So, any ideas? We have DL385 G2s on RHEL 5.2 so something in 5.3 isn't playing well with the same hardware. We've tried factory resetting the BIOS, etc. How do I work out what the kernel's up to? (I've already removed "rhgb quiet" from the append line.) Luckily we don't have too many of these boxes and I have a little time to investigate.
