Bug#737938: BUG: unable to handle kernel paging request at 000008000000001c
After replacing the bad memory and reinstalling Debian from scratch, I have had no further problems. I am assuming that the symptoms of this bug report were caused by the bad memory. You may close this bug report at your convenience. I've made a new friend: memtest86+, which I will use on all systems with non-ECC memory from now on. Thanks for the tip! -- .''`.

Did you run memtest86+ or other memory test yet? I'm not used to systems that don't automatically check their memory, as all my old i386 systems do. And I hate non-ECC memory, which this system uses. But your hunch was right. memtest86+ revealed a bad memory DIMM, which makes my entire installation suspect. New memory is on order. I'll reinstall Debian from scratch once the new memory has been installed and tested. -- .''`.
