Data Cache Push Parity Error
Hi all, I am using P2020 with Linux kernel 3.8.13. Sometimes my system encounters machine check exception and it shows “Caused by (from MCSR=2000): Data Cache Push Parity Error”. Could anyone show me some hints to dig into this issue? Any comment is welcome. Thanks in advance. Jay Chen… This electronic mail transmission is intended only for the named recipient.

MPC8548 eTsec
Dear All: I am using linux 2.6.14.5 (with many modification) and MPC8548. Sometimes(very rare) the nic will boot up with rx problem. (tx is just fine) I see pkts are all dropped in chip but no any RX or BSY interrupt are ever raised. (Receive Drop Counter is increased) If I down and up the nic, the problem will gone. Any suggestion is welcome. Thanks. Jay...
