From: =?iso-8859-1?B?QXVy6WxpZW4gTely6Q==?= <[EMAIL PROTECTED]> To: "Marius Strobl" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Subject: Re: kern/128833: [bge] Network packets corrupted when bge card is in 64-bit PCI slot Date: Wed, 19 Nov 2008 02:27:43 +0100 Concerning the problem described by davidch@ , my chip is reported as a B5 revision (01050000), so it might not be the case here. You're right, the M/B doesn't support PCI-X at all. As detailed on the manual, the NB chipset (AMD762) provides support for 2x66 MHz 64-bit PCI 2.2 masters, and the SB chipset (AMD768) provides a secondary PCI 2.2 bridge 33MHz. I tried the patch but it didn't solve the problem, whilst the BGE_FLAG_PCIX was no longer in the flags, which seems much more correct anyway. At the end of the initialization values are these, as planned : bge_flags = 0x0010180F (0x10100F | BGE_FLAG_64BIT) . BGE_PCI_PCISTATE is unchanged Note I forgot to mention the BGE_FLAG_RXALIGN_BUG (100000) and BGE_FLAG_TBI (1) last time, as I tested before reset of the chip where these flags are set. ----- Original Message ----- From: "Marius Strobl" <[EMAIL PROTECTED]> To: "Aurélien Méré" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Tuesday, November 18, 2008 11:46 PM Subject: Re: kern/128833: [bge] Network packets corrupted when bge card is in 64-bit PCI slot > On Mon, Nov 17, 2008 at 02:37:51AM +0100, Aurlien Mr wrote: >> Hi >> As first check, when device is being attached, here are the values >> reported >> and the diff : >> >> in 32 bit slot : >> BGE_PCI_PCISTATE = 0x96 (0x86 | BGE_PCISTATE_32BIT_BUS) >> bge_flags = 0x120E (0x100E | BGE_FLAG_PCIX) >> >> in 64 bit slot : >> BGE_PCI_PCISTATE = 0x8E (0x86 | BGE_PCISTATE_PCI_BUSSPEED) >> bge_flags = 0x1A0E (0x100E | BGE_FLAG_PCIX | BGE_FLAG_64BIT) >> >> Seems logical so far, I'll try to look further. > > Apart from the problem described by davidch@ (I'm not sure > you actually have a BCM5701 A3 though, at least bge(4) doesn't > seem to be aware of that revision) the BGE_PCI_PCISTATE and > bge_flags pairs you reported don't match though; according > to BGE_PCI_PCISTATE the card isn't in a PCI-X slot in either > case (BGE_PCISTATE_PCI_BUSMODE is always set, which means > PCI) and AFAICT your motherboard chipset also doesn't > support PCI-X.
