Now collected. The problematic commit is: bad: [292dd876ee765c478b27c93cc51e93a558ed58bf] Pull release into acpica branch The longer story follows (and I'll file it with the bugzilla). The bug is that S3 sleep hangs on the second sleep of my TP 600X, producing an endless loop in the dmesgs (across a serial console): exregion-0182 [30] ex_system_memory_space: system_memory 0 (32 width) Address=0000000023FDFFC0 exregion-0182 [30] ex_system_memory_space: system_memory 1 (32 width) Address=0000000023FDFFC0 exregion-0287 [30] ex_system_io_space_han: system_iO 1 (8 width) Address=00000000000000B2 exregion-0182 [29] ex_system_memory_space: system_memory 0 (32 width) Address=0000000023FDFFC0 'git bisect' narrowed the problematic commit to: commit 292dd876ee765c478b27c93cc51e93a558ed58bf Merge: d4ec6c7cc9a15a7a529719bc3b84f46812f9842e 9fdb62af92c741addbea15545f214a6e89460865 Author: Len Brown Date: Fri Jan 27 17:18:29 2006 -0500 Pull release into acpica branch This commit had a slightly different bug from all the other ones I marked as bad. This one hung on the first S3 sleep, with the same endless loop pattern as the other bad ones (but they hang on the second S3 sleep).
