Every now and then I get:
Jan 28 19:05:18 yedi /kernel: de0 <Digital 21140A Fast Ethernet> rev 34 int a ir
q 14 on pci0:9:0
Jan 28 19:05:18 yedi /kernel: de0: can't find phy 0
Jan 28 19:05:18 yedi /kernel: de0: can't read ENET ROM (why=-4) (462601000000000
000000000000000006b00030100c0f03041fb001e00000008
Jan 28 19:05:18 yedi /kernel: de0: 21140A [10-100Mb/s] pass 2.2
Jan 28 19:05:18 yedi /kernel: de0: address unknown
during boot. This is 2.2.8-stable, the card is a Kingston PCI 10/100 mbit.
Only a power cycle fixes it.
Looks like:
/*
* Make sure there won't be any interrupts or such...
*/
TULIP_CSR_WRITE(sc, csr_busmode, TULIP_BUSMODE_SWRESET);
DELAY(100); /* Wait 10 microseconds (actually 50 PCI cycles but at
33MHz that comes to two microseconds but wait a
bit longer anyways) */
if ((retval = tulip_read_macaddr(sc)) < 0) {
#if defined(__FreeBSD__)
printf(TULIP_PRINTF_FMT, TULIP_PRINTF_ARGS);
#endif
printf(": can't read ENET ROM (why=%d) (", retval);
for (idx = 0; idx < 32; idx++)
printf("%02x", sc->tulip_rombuf[idx]);
handles this. Could it be that the DELAY is too short? The mainboard is
an Asus T2P4 btw. When the card gets probed successfully it works like
a charm.
