Hello,

Lastest sky2 update between 2.6.21-rc7 and 2.6.21 final disables the support of the integrated ethernet adapter build on the Asus P5B-E Plus motherboard.

Code used is :

#ifdef broken
/* This device causes data corruption problems that are not resolved */
{ PCI_DEVICE(PCI_VENDOR_ID_MARVELL, 0x4364) }, /* 88E8056 */
#endif

I use this hardware successfully daily for one month and without any sign of problem (no corruption, no timeout, no warning) with kernel 2.6.20, x86_64.
Defining "broken" in sky2.h make it work again in 2.6.21 (but i did not run extended tests).
