[linux-laptop] RE: S3 slow resume

[sdfa]

i've tried turning dma off with "hdparm -d 0 /dev/hda" and then sleeping/resuming with the same results. i've also read that enabling "Use multi-mode by default" in my kernel would fix errors like the ones reported, but it hasn't worked for me.

Subject: S3 slow resume



i've got a sony vaio with slackware 10.2 and a 2.6.13.4 kernel on it. i've been pretty successful getting S4 to work but i've had a few issues resuming from S3. Basically, this is what happens when i do an "echo mem > /sys/power/state": it goes into sleep mode: my power indicator light starts slowly blinking red(i guess that means it's asleep, i think it did this with standby in windows, too).<br><br>without the acpi_sleep=bios_s3 parmaeter, when i hit a key, the light turns green(like it's back on) but the screen doesn't come back. with the parameter it resumes like this:<br>[code]<br>inu<br><br><br>Back to C!<br>ipw2200 error -22<br>ACPI: PCI Interrupt 0000:00:02.0<br>...<br>[/code]<br>is that normal? the "inu" and "back to c!" stuff seem kinda wierd. after this wakeup stuff(about 30 seconds), i get a prompt and anything i enter in it just kinda ... does nothing. so its like:<br>[code]<br>root at slink:~# ls <return><br><blank line> <return><br><blank line> <return><br><blank 
line> <return><br><blank line> <return><br><blank line> <return><br>asdfdsaf<br>wtf ??????<br><blank line> <return><br><blank line> <return><br><blank line> <return><br>[/code]<br>its as if i'm in a program that has crashed and i cant break out of it. at this point i still have keyboard control, etc. but i cant ctrl+alt+del to reboot and i cant actually do anything. after about 2 minutes of this, i hear a little whir(the hd spin up maybe?) and everything works(successful suspend/resume) but that's way too long, i could have used S4 and resumed faster than that. is there anything i can do to speed up my resume from S3?<br><br>_______________________________________________<br>Join Excite! - http://www.excite.com<br>The most personalized portal on the Web!<br><br>
