HI,
Current version of Seabios is causing blue screen on Windows2003 when 64bit PCI resource is present and occupies high memory.
BSOD Error code is: 0x000000A5 (0x02, 0xFFFFfADF6A446880, 0x1, 0xFFFFFADFAA34690)
The issue is localized, it is related to presence of 64bit resource in _CRS method.
If we disable a 64bit region from _CRS the Win2003 load normally but this doesn't allow Windows to use 64bit resources.
At the moment I have no idea how to fix this. Please help!
Unfortunately, it's very difficult to debug acpi issues on Windows. Gerd's been on vacation this week - so, lets give him a chance to look at it when he gets back. If it can't be resolved, we'll need to revert the patch that broke Win2003.
P/S Yet another issue is related to debug messages. If I add any DBUG call in acpi-dst it will cause BSOD on win2003 (win2008 works fine)
I've seen this as well (on WinXP - I don't have Win2003). Unfortunately, I haven't been able to find out why the debug macro fails on these older versions of Windows. -Kevin

Hi Kevin,
Unfortunately, it's very difficult to debug acpi issues on Windows. Gerd's been on vacation this week - so, lets give him a chance to look at it when he gets back. If it can't be resolved, we'll need to revert the patch that broke Win2003.
Thank you for your reply. Right - acpi issues are painful. Actually I'm on a long holidays too. I'll do my best if you or Gerd need any help with the issue. Kind regards, Alexey

Well, it isn't a regression, so no need to revert IMHO. It breaks on winxp / win2k3 only in case 64bit pci is actually used. Which happens only in case we run out of address space below 4G. This is a setup which isn't supported at all with older seabios versions. The very first patch revision had a static entry in the _CRS array (before _CRS became a method) which didn't work with winxp too. So we ended up with the _CRS method which (beside updating the 32bit window) adds the 64bit RessourceTemplate only in case we actually have 64bit pci ressources, so we don't disturb existing setups with a new 64bit entry they might not be able to handle. I've never seen 64bit RessourceTemplate entries work with winxp, I fear the winxp acpi code just can't handle 64bit RessourceTemplates ... cheers, Gerd
