Dear all, i report this issue, as requested in the discussion in bugs.debian.org. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=571251 Honestly, i am still not sure this issue is really ACPI-BIOS related. PC hangs at boot between 30 and 50% of the times. Sorry, but i can describe the issue only visually, since i can find no dmesg traces or logs on the hd. I switch on the PC, GRUB load the boot menu correctly, always. Then, i select the kernel entry for loading. Between 2.6.30 and 2.6.34 there are some little differences, but pc hangs in any case: 2.6.30 -Let's say after 2 seconds i see the WIFI led to become blue, and see some HD activity. -just after i see just two lines of the boot message: Fail in evaluating the _REG object of EC devices. Broken BIOS is suspected Loading, Plese wait Then the cusrsor stop to blink and PC hang completely. 2.6.34 -Let's say after 2 seconds i see the WIFI led to become blue, and see some HD activity. -just after, i see just two lines of the boot message: [1.111781] pci 000:01:00.0: no compatible bridge window for [mem:0xfff80000 -0xffffffff pref] [1.111789] pci 000:03:00.0: no compatible bridge window for [mem:0xfff80000 -0xffffffff pref] Then the cusrsor stop to blink and PC hang completely. Many thanks, Regard, Angelo

Dear Zhang Rui, i have tried the acpi=off, it works, i have tried removing b43 and ssb modules, it works So i would say, yes, it is the same bug. Workarounds above works for me. Many thanks, Angelo *** This bug has been marked as a duplicate of bug 14716 ***
