Red Hat Bugzilla – Bug 36978
apm suspend crash on wakeup with a Toshiba Tecra 8100
Last modified: 2014-03-16 22:20:26 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-2 i686) suspending the laptop with apm --suspend works (The control led confirms this). When powering up, all I get is a blank screen (keyboard doesn't work....not even the powerbutton. All that is possible is using the hard-reset). I'm using a Toshiba Tecra 8100 with RH7.1 installed on the loop device (on a vfat partition). apm --suspend however did work with RH7.0 in the exact same configuration. Reproducible: Always Steps to Reproduce: 1. apm--suspend 2. power back on 3. Actual Results: system crashes. Keyboard and powerbutton are not responsive to input. Power Led stays on. Expected Results: system-wake up Toshiba Tecra 8100 256 Mb RAM HD 6G (3+3 vfat, the Redhat.img is on partition 2 with a size of 2G)
downgrading to the apm rpm from RH7.0 solves the problem
This bug looks old, but it's still open, so here's a comment. On the Dell Inspiron, this happens when DRI is enabled in X and the machine is suspended---it does not restore. See the information on suspending in the Linux-Dell-Laptops FAQ at http://www.whacked.net/ldl/faq With the latest 7.1 updates for X and the kernel, this problem has re-appeared since DRI is now enabled by default. I'll probably submit a new bug report.
The laptop is still running RH7.1 (but not on an vfat partition anymore). The apm problems still occurs (even with the RH7.0 apm RPM... I though for a moment it worked better, but I was wrong) Because of the previous comment I tried some suspends without X... and it seemed to work. The RH7.0 installation (which didn't have the problem), used a Xfree3.x X- server not included in RedHat. So I think the problem can be traced back to X.
Are you still seeing this with the current version?
not suring if you're asking about this question as regards Toshiba or Dells, but this is still a problem on the Dell Inspiron. one thing to add is that the module agpgart cannot be loaded *before* doing the suspend (i'm not sure what the relationship is between DRI and agpgart).
DRI and/or AGPGART are not loaded on the Toshiba 8100 (the S3 Savage only has 2D accelleration in linux), also no kernel modules are loaded for X. I am not really able to try a new RH version on this machine because it's now used as a "stable" development platform. If I have time this week I will try the newer X version. I will keep you posted.
If downgrading APM solved the problem before, then it most likely is not an XFree86 issue. APM related problems usually are not XFree86 related, but tend to be hardware bugs or BIOS bugs which potentially can and sometimes do get worked around in kernel updates or fixed in BIOS flash updates. Also, kernel bugs, apmd bugs. XFree86 bugs do pop up, but the are indeed rare. Almost all APM bugs that get resolved are not resolved via XFree86 updates. Reassigning to apmd
Closing out bugs on older unsupported releases. Apologies for any lack of response. Please reopen if it persists on current releases such as Fedora Core 3.
