Hello Xin, > I got a strange problem when having HTT enabled on a P4 2.8E > processor. When rebooting the system, after the disk sync and > the system is going to restart, it crashes and generates a > crashdump. Strangely, the panic message seems to be corrupted. That's exactly what I'm seeing on P4 3.0E (yes, also `E') and Intel S875WP1-E motherboard ftp://download.intel.com/support/motherboards/server/s875wp1-e/tps.pdf , but it even doesn't do crashdump, just freeses. And not each time but maybe 3-4 of 5 reboots. BTW running `halt' instead of reboot worked. Sorry I didn't had time this night to try a kernel with debugging. > The system used to crash before sync'ing disks. It seems that > Nate's recent commit has removed that crash. More information > available upon request. Exactly. 5.2.1-R and -CURRENT of late May were also tested, they were crashing before syncing discs, 20040614 -CURRENT crashes (freeses) after syncing. People say that on older P4 CPUs (Northwood core) that do not have this problem, only on `E'-s (??? Strange enough). WBR, Andrew
