Dear kernel developers, Hillf, Mike, Boris and Tony,
Hello. It's been a long time since I last replied this email, and I don't know if it's appropriate to reply all of you in one letter.
I've tried out most of the suspects you told me, and here's the results:
-- Panic DON'T happen when the laptop is running on battery. I've tried over 20 battery cycles (~40 hours) doing video playbacks and the computer never shut down. -- Panic DO happen when: (1) I removed the secondary SSD and the tray, or when (2) bbswitch module isn't functioning (i.e. the nVidia card is on), or when (3) the laptop runs on AC without battery. -- I don't know anyone with exactly same model or hardware with me. But I asked some friends with similar hardware and they don't have similar problem. -- I ran memtest86+ for a whole night (over 10 passes) and nothing goes wrong. -- There is something wrong with my hard drive (one sector redirect reported by SMART 0x05, failure reported with value 1 in 0xB8, and another old failure in 0xBE; it's a little old), and sometimes it halts and panics between fscking rootfs and fscking /home (I don't know why and don't have the logs), but I did a long test with Seagate's SeaTool and it passed. -- The panics happen when using Google Chrome's Flash plugin to play videos and *audios* and when using mplayer to play videos, but don't happen when playing local audios (mp3/flac).
I start to think that it's only me that have this problem, and may never be able to get fixed. But I'll still be a Linux desktop user no matter what.
Big thanks to all of you and all of the kernel developers for your help and great job.
