There had been no functional changes for very long time so I'm not sure what's going on here. I've attached local change I have at this moment but I'm afraid it wouldn't address the issue above. I recall jhb also reported interrupt storm in the past but the root cause was not identified yet. Could you change msk_intr() and let me know which interrupt is firing? > > Here is some additional info: > ----- > mskc0@pci0:3:0:0: class=0x020000 card=0xff501179 chip=0x435511ab > rev=0x12 hdr=0x00 > vendor = 'Marvell Technology Group Ltd.' > device = '88E8040T PCI-E Fast Ethernet Controller' > class = network > subclass = ethernet > cap 01[48] = powerspec 3 supports D0 D1 D2 D3 current D0 > cap 05[5c] = MSI supports 1 message, 64 bit enabled with 1 message > cap 10[c0] = PCI-Express 2 legacy endpoint max data 128(128) link x1(x1) > speed 2.5(2.5) ASPM disabled(L0s/L1) > ecap 0001[100] = AER 1 0 fatal 0 non-fatal 1 corrected > ecap 0003[130] = Serial 1 b8b063ffff681e00 > ----- > > -- > WBR, Boris Samorodov (bsam) > FreeBSD Committer, http://www.FreeBSD.org The Power To Serve --HcAYCG3uE/tztfnV Content-Type: text/x-diff; charset=us-ascii Content-Disposition: attachment; filename="msk.link.diff" Index: sys/dev/msk/if_msk.c =================================================================== --- sys/dev/msk/if_msk.c (revision 257303) +++ sys/dev/msk/if_msk.c (working copy) @@ -4071,12 +4071,12 @@ CSR_WRITE_4(sc, B0_IMSK, sc->msk_intrmask); CSR_READ_4(sc, B0_IMSK); + ifp->if_drv_flags |= IFF_DRV_RUNNING; + ifp->if_drv_flags &= ~IFF_DRV_OACTIVE; + sc_if->msk_flags &= ~MSK_FLAG_LINK; mii_mediachg(mii); - ifp->if_drv_flags |= IFF_DRV_RUNNING; - ifp->if_drv_flags &= ~IFF_DRV_OACTIVE; - callout_reset(&sc_if->msk_tick_ch, hz, msk_tick, sc_if); } --HcAYCG3uE/tztfnV--
