I changed my kernel config today: e1000 is now "=y" (was "=m"), I removed PCMCIA as I do not use it and some other modules complained about it, and I added CONFIG_HIGHMEM4G=y (was CONFIG_NOHIGHMEM=y) The running kernel is 2.6.22.5 +cfs +squashfs. My distribution is gentoo (x86), quite up to date, udev is 104-r12. Please CC me as I'm not subscribed to the list.
