Checking Google news, I see that jhb has worked in pci_cfgreg.c for similar issues. Plus your web site would not work with Mozilla Firebird 0.7 (win) It wouldn't take the graphic code. >How-To-Repeat: >Fix: I took the pci_cfgreg.c from the 5.1 install and put it in the 5.2.1 install and recompiled the kernel (with some hopefully nonessential config changes, I removed the commmented out pci line) and it worked. I got irq4 for the serial mouse and dmesg looks ok. The commented out pci line was tried first in a recompile of the kernel so I'm pretty sure that it's the .c file. >Release-Note: >Audit-Trail: >Unformatted:
