It should still do wake-on-lan, although the fxp driver doesn't support that right now - it doesn't appear to be a useful feature. Powersave transitions (D0 -> D3) should also still work. What the fix does is prevent the board from reducing power in idle state, which is a subset of D0. (Intel has D0-active and D0-idle, or some such). -- Jonathan To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

I think I'll drag this into my local 4.3 based source tree, when I get some time. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Re: fxp SCB timeout problems [FIX]
Its looking great so far! In the two production machines I put it in last night, zero time outs as expected!! These are both EM machines. On my two internal ET machines, also zero problems. The machines are in 10BaseT/UTP, and 10BaseT full duplex. inphy0: on miibus1 inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto and fxp0: port 0xdf00-0xdf3f mem 0xff6ff000-0xff6f irq 11 at device 8.0 on pci1 fxp0: Ethernet address 00:03:47:6f:f7:e0 inphy0: on miibus0 inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto Thank you *VERY* much for fixing this problem. ---Mike At 01:43 PM 8/26/01 -0400, Mike Tancsa wrote: >I have it on two machines with this chipset and it looks good so >far.

fxp SCB timeout problems [FIX]
I believe that I have a real fix for the SCB timeout problems that have been plauging users of recent Intel fxp boards. If you have a board that uses the Intel ICH2/ICH2-M chipset (usually 815E style boards) and feel comfortable applying patches to the system, please contact me to test a fix. The patch works on two different boards here, but I would like to get some wider testing before I commit it to the tree. -- Jonathan To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
