Distribution: gentoo Hardware Environment: Toshiba Satellite A15-S1292 Software Environment: ACPI enabled, APM disabled Problem Description: ACPI generally works well including Toshiba extensions. Suspend-to-RAM works perfectly the first time with the power led flashing amber after suspend. Resume also proceeds without any difficulty. However, on the second suspend attempt the screen blanks but the power led remains solid green. The system is entirely unresponsive except until (hard) powered down and restarted. Including the /var/log/debug for success and failure cases. It seems in the second attempt it never reaches the enter_state call in kernel/power/main.c. Sorry for posting to the bugzilla-list, missed the correct link. Steps to reproduce: 0) [Boot] 1) [Suspend] acpitool -s (or echo 3 >/proc/acpi/sleep) 2) [Resume] PWR button 3) [Suspend] acpitool -s [hangs]

Created attachment 4217 [details] /var/log/debug after reboot from hang following second suspend
Please try to unload sound card driver and USB driver before suspend. The drivers caused many similar issues. Thanks.
I unloaded all USB and sound modules but found the same behaviour. I checked the logs and they are identical to those posted previously. If there is something I can do to extract more revealing information please let me know. Thank you.
Try disabling DRI - this seems to occur with some video drivers.
Please reopen this bug: - if it is still present in recent 2.6 kernels and - you can answer Matthew's question.
