Description of problem: My IBM Thinkpad R51, with the latest Fedora kernel (2.6.10-1.741_FC3) will not wake up from sleep. The system actually wakes up fine, after s3 sleep, but the display doesn't come back up making the laptop rather useless Version-Release number of selected component (if applicable): 2.6.10-1.741_FC3 How reproducible: 100% Steps to Reproduce: 1. echo 3 > /proc/acpi/sleep 2. Close lid 3. Open lid Actual results: Display doesn't come back up. Nothing in /var/log/messages gives me anything useful. I tried waking up the display by pressing the button to wake/dim the display, and there was a no go Expected results: Wake up from sleep Additional info: tried to append acpi_sleep=s3_bios during bootup, and nothing happened So what I do is I do ctrl+alt+f1, login as root, then reboot. All without seeing things ;-) Tried this without ipw2100 loaded as well, and even without X started 00:02.1 Display controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02) Thats the display adapter from lspci
Appended acpi_sleep=s3_bios to bootup, do echo -n 3 > /proc/acpi/sleep, using the 2.6.11-1.1240_FC4 kernel from rawhide makes the laptop sleep and wake up sanely. pm-utils is also installed (pm-utils-0.01-1.i386), so it looks like r51 sleep will work with FC-4
