kernel 3.2 crashes too early on HP dc7700 and HP t5000 series
Hello,
I've tried to test the recently released 3.2 version on a couple of my PCs (one is HP dc7700, an SFF PC running on Intel E6300, another is HP t5710 thin client running Transmeta's Efficeon). In both cases the kernel crashed during the first seconds the control was given to it by the bootloader.
I decided to investigate, so I've compiled a version using 'make allnoconfig' - and it has crashed with the same symptoms: once the kernel gets the execution control a screen is filled up with random colour rubbish and after 15 seconds or so my LCD turns off into the power saving state. The machine looks to be locked up since it doesn't react on the keyboard.
Well, I thought that an early printk's may help me to determine what's going on so I recompiled the kernel with them + a couple of other debugging options (like x86 bootup debugging code), but after I rebooted into the newly compiled kernel I got the very same lock-up.
Both these PCs are running fine with 3.1.5 and I'm now downloading 3.1.8 (just to confirm that 3.1 series are working on this hardware).
This message is just to notify the community that there is some issue with 3.2 on old HP hardware. I'll try to figure out what's wrong and if I find anything I'll post a follow-up.
I'd appreciate any hints on how to debug this kind of crashes. Right now, I'm thinking re: adding some dirty debugging code into the kernel initialisation just to figure out where it crashes.

Thanks for doing that, however, I'm a bit concerned that my e-mail address is now exposed there (that bugzilla doesn't obfuscate or protect e-mail addresses -- which is quite concerning), is there any way how to remove my primary work e-mail from that page? Or at least to replace it with "[email protected]"?
Thanks!
