boot messages from 2.4.26-rc1 kernel on P4C800E-Deluxe
For 2.6.5 behaviour see bug http://bugzilla.kernel.org/show_bug.cgi?id=2056 , where is attached full output of vanilla 2.6.5 kernel on that very same host. No, I got this problem also on 2.6.5 now, so #2 points you to case when it used to work. Now it doesn't. See attachment. Created attachment 2497 [details]
2.6.5 doesn't fail
Comment on attachment 2497 [details] 2.6.5 doesn't fail Sorry for comment #3, 2.6.5 doesn't fail. Should go sleep now. ;( >evregion-0251 [24] ev_address_space_dispa: No handler for Region [BIOS] (c1c3ec54) [SystemMemory] > exfldio-0283 [23] ex_access_region : Region SystemMemory(0) has no handler Bob, sounds like an ACPI CA issue. Martin, could you please provide the acpidmp, so bob can reproduce it. Created attachment 2499 [details]

Since acpidisam doesn't work well, would you please send me /proc/acpi/dsdt. Thanks, Luming Bob, looks like the _PRW is a method. And the method is executed before namespace region is initialized(that is current implementation). So current _PRW support cann't work if _PRW is a method. I think ACPICA should defer executing _PRW. Note that the bug described in http://bugme.osdl.org/show_bug.cgi?id=2403 has been tracked by Bob and myself and that the problem is know known. Here is the last mail from Robert I received. So This bug can be closed as a duplicate... --------------------------------------------- I've found the problem, the _PRW is accessing an Operation Region before the default region handlers are installed. This will take a bit of work to figure out a solution. Bob --------------------------------------------- Created attachment 2519 [details]
