--SNIs70sCzqvszXB4 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi. I just upgraded my laptop (Dell Latitude C610 A16 BIOS) to CURRENT and most things work dandy. However, I'm having trouble getting power management to work. Suspending the laptop is abig deal for me, so I'd like to get a decent workaround or fix and I'm happy to help. Here are the details. With ACPI enabled, sleeping to S1 leaves the LCD on and fan running, sleeping to S3 suspends the way apm did under 4.9, but immediately after suspend is complete (screen goes out, fan stops) the keyboard LEDs flash and the system reboots from power off. Not so good. I can't turn ACPI off, because I panic (page fault in supervisor mode) on boot up. It looks like pcib is expecting acpi to be there, though it isn't. Apm worked fine under 4.9, so I think if I could get ACPI out of the way, I could use apm again and be happy. I've tried many combinations of partially disabling ACPI and kernels with and without SMP and apic. This is really easy to reproduce with GENERIC, and I'm happy to experiment and pass on debugging results if someone's interested in the data. Let me know what you need. I'd love to get this working, so I can play with -CURRENT more. -- Ted Faber http://www.isi.edu/~faber PGP: http://www.isi.edu/~faber/pubkeys.asc Unexpected attachment on this mail?
