자료실에 있는 커널 2.6.11을 오늘 EZ-X5 보드에 올려 보았습니다.
아래 어느분이 올리신 글 처럼 이더넷의 속도가 왠지 모르게 느리다는
생각이 들고 ftp가 느리게 움직이는 현상이 나타납니다.

ping으로 측정해보면 2.4커널과는 0.1ms 정도 차이를 보이지만 거의
비슷한 수준이라고 생각이되더군요.
계속 ping을 걸어 보았지만 패킷 에러율은 0%가 나타나고 특이점을
찾을 수 없었습니다.

하지만 파일을 큰것을 ftp로 가져오다 보면 어느 경우 ftp가 멈추는 현상
같은것이 보입니다.
물론 그 상태에서 다시 ping을 해보면 잘됩니다.

저는 아래분처럼 키보드 속도 문제는 없는것 같습니다.

그리고 추가적으로 자료실에 올라와 있는 커널에는 FFUART가 FULL로
IRQ가 허가되어 있지 않코 BTUART도 IRQ가 허가되어 있지 않터군요.

그부분은 arch/arm/mach-pxa/ez_x5.c를 수정해야 하더군요.

컴파일 환경은 gcc-3.4.5 이구 Cygwin에서 컴파일 했습니다.
