Summary: sleeping function from invalid context during suspend. (acpi_pci_link_set calls kmem_cache_alloc) https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=154046 ------- Additional Comments From [EMAIL PROTECTED] 2006-02-11 01:11 EST ------- I have a Dell Latitude D610, and I notice the same thing: when suspending on the 2.6.14-1.1656_FC4 kernel, it says "sleeping function called from invalid context" and then hangs after suspend. However, there is an even stranger twist. When I patched this kernel with Software Suspend 2 (swsusp2) (note: this is for suspend-to-disk), and THEN tried suspend-to-RAM, it worked just fine (although the same debug message occurred). This seems incredibly strange to me, and I don't see how this patch could affect ACPI functionality at all. (Note: for anyone who wishes to try this, swsusp2-patched Fedora kernel RPM's are available at http://mhensler.de/swsusp/ ... the 2.6.14-1.1656 patched kernel worked for me.) Even stranger: when I got the swsusp2-patched 2.6.15-1.1825 kernel, suspend-to-RAM no longer works. The debug message is gone, but the system hangs after suspend. Very, very strange.
