Yesterday after finally updating to a curren= t=20 that boots my system after a couple of weeks without it I suspended the=20 system and resumed it to check some ACPI issues had been fixed, but that's= =20 for another time. After resume I realized I needed my mouse, so I plugged i= t=20 in, dynamically loaded the kernel module and the mouse worked (normal/ previous). Then I suspend the laptop and was wiggling the mouse while it w= as=20 suspending (bad habit from testing) and the system REBOOTED, and my patches= =20 weren't even applied! Strangly enough I had never actually tested this=20 situation before, so I had assumed it was my code that was the problem. =20 There seems to be some ACPI problem, since I just tested the same procedure= =20 on with ACPI disabled and there was no reboot. http://am-productions.biz/debug/acpidump.txt http://am-productions.biz/debug/littleguy.dsdt http://am-productions.biz/debug/littleguy.asl http://am-productions.biz/debug/dmesg.txt dmesg attached too. =2D --=20 Anish Mistry =2D----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQE/j0tUxqA5ziudZT0RAsnDAJ48ehUGVPnMWXgJbmAxPw9zg1p9OACgvy2s JO25mUFwvByJiUyPPnAvsr8=3D =3D8fK2 =2D----END PGP SIGNATURE----- --Boundary-00=_Ft0j/vsoXi8U8AG--
