Bug#419713: linux-source-2.6.18: Null pointer dereference, kswapd died
Package: linux-source-2.6.18
Version: 2.6.18.dfsg.1-12
Severity: important
During normal system use, experienced lockup. Not a full panic, but still required a hard reboot.
This could be related to another bug already listed, but there are so many I couldn't pick through them all.
