I've had lockups with self-compiled 2.6.25 kernels on other hardware as well, all related to hpet_rtc_interrupt; see the LKML archive for the details. This is the first time I've tried a Debian-packaged 2.6.25, and it also hangs. The workaround recommended on LKML was to disable CONFIG_HPET_EMULATE_RTC (it cannot be disabled in the menu, you have to edit the configuration by hand). This workaround seems to work for me: $ uname -a Linux boogie 2.6.25 #3 SMP Thu Jun 12 13:32:35 CEST 2008 x86_64 GNU/Linux $ uptime 15:57:16 up 15 days, 1:43, 13 users, load average: 0.24, 0.57, 0.65 Without the workaround, I never got an uptime more than a couple of hours. So I suggest applying the workaround to the Debian package as well.
