We have had this exact problem several times. It has always turned out to be that the platform monitor card needed replaced.

Hi !
You have to update the GSP firmware and may be your Hardware Enablement Patches. Take a look at this threads :

Re: System Hang Detected via timer popping

Hi,

the Alert Level 13 Message simply means that the GSP does not get heartbeat chassis codes from the operation system (HPUX) => system hang.
This means that the kernel is not running properly anymore. The cause can be either a bad or missing patch or a hardware cause. If it happens during bootup, I would suspect an I/O timeout problem (try unplugging all cables and non boot disks). The best way to troubleshoot this hangs is to enter "tc" on the GSP prompt (CTRL-B on the console) to produce a memory dump. The dump can be analyzed by HP support.
Another possible troubleshooting attempt would be to boot from the install CD to a recovery shell. If the system hangs then, it is a hardware problem with a high chance. You should carefully examine the consolelog ("cl" on the GSP prompt) for error messages.
By the way, a GSP update will not help and the A-Class does not have a platform monitor card (is part of the system card on A-Class/rp24x0).

best regards

Stefan
