Summary: After wakeup from suspend to disk, machine loops in
memory clean up
Product: Memory Management
Version: 2.5
KernelVersion: 2.6.22.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Page Allocator
AssignedTo: akpm at osdl.org
ReportedBy: sbuehne at web.de
Most recent kernel where this bug did not occur: 2.6.21.5 (latest version used
before)
Distribution:
Hardware Environment: 1GB RAM, Intel Pentium M ICH6
Software Environment: Kernel 2.6.22.4, KDE 3.5.7. ATI display driver version
8.40.4-x86.x86_64
Problem Description:
Use "Suspend to disk" feature. After resuming from this, the machine loops in
memory management, by trying to clean up the memory. By monitoring the memory
usage you can see that the kernel tries to clean up the whole memory. The
memory usage stays below 100MB, whereas more then 500MB was in use before
supsend.
Therefore the machine becomes unusable because of extensivly page in/page out
activity and must be rebooted.
Steps to reproduce: Run "Suspend to disk" several times. After resuming the
problem occurs.
