Commit > 96990a4ae979df9e235d01097d6175759331e88c took its place. I did a grep through the kernel changelogs for this commit: $ grep 96990a4ae979df9e235d01097d6175759331e88c * ChangeLog-2.6.22.19: patch 96990a4ae979df9e235d01097d6175759331e88c in mainline. ChangeLog-2.6.23.15: patch 96990a4ae979df9e235d01097d6175759331e88c in mainline. ChangeLog-2.6.24:commit 96990a4ae979df9e235d01097d6175759331e88c Or: this commit should have been included in kernel 2.6.24. But the PAE memory leak I observed still occurs with 2.6.24.2. So the question remains: is there already a fix available for the problem I observed ?
