Hi, Thanks for the response! We found a different solution / approach which seems to work on both RELENG_4 and RELENG_5. The problem is that the modem is not being seen as a PCI / PUC device and instead is being seen as an ISA SIO device ?? The following RELENG_5 and RELENG_4 patches seem to fix the problem. I wonder if the other modems listed in sio.c suffer the same fate ? Also fixed in this are those "cant re-use leafs" at bootup time. The modem is seen as a PUC device now.... At the bottom is a diff between the boot -v (Patches are done by keith_at_sentex.ca) --- orig/sio_pci.c Thu Sep 9 15:44:19 2004 +++ sio_pci.c Thu Sep 9 14:51:16 2004 _at__at_ -76,7 +76,9 _at__at_ { 0x048011c1, "Lucent kermit based PCI Modem", 0x14 }, { 0x95211415, "Oxford Semiconductor PCI Dual Port Serial", 0x10 }, { 0x7101135e, "SeaLevel Ultra 530.PCI Single Port Serial", 0x18 }, - { 0x0000151f, "SmartLink 5634PCV SurfRider", 0x10 }, +/* Removed 2004/09/09 - KDW + { 0x0000151f, "SmartLink 5634PCV SurfRider", 0x10 }, +*/ { 0x0103115d, "Xircom Cardbus modem", 0x10 }, { 0x98459710, "Netmos Nm9845 PCI Bridge with Dual UART", 0x10 }, { 0x432214e4, "Broadcom 802.11g/GPRS CardBus (Serial)", 0x10 }, releng-5-pioneer# diff -u orig/pucdata.c pucdata.c --- orig/pucdata.c Thu Sep 9 15:45:33 2004 +++ pucdata.c Thu Sep 9 15:00:43 2004 _at__at_ -818,6 +818,17 _at__at_ }, }, +/* ADDED 2004/09/09 - KDW - { 0x0000151f, "SmartLink 5634PCV SurfRider", 0x10 }, */ + /* "SmartLink 5634PCV SurfRider */ + { "SmartLink 5634PCV SurfRider", + { 0x151f, 0x0000, 0, 0 }, + { 0xffff, 0xffff, 0, 0 }, + { + { PUC_PORT_TYPE_COM, 0x10, 0x00, COM_FREQ }, + }, + }, +/* END KDW */ + /* US Robotics (3Com) PCI Modems */ { "US Robotics (3Com) 3CP5609 PCI 16550 Modem", { 0x12b9, 0x1008, 0, 0 }, releng-5-pioneer# vmstat now sees that the PUC device shares the interrupt and all seems well! releng-5-pioneer# vmstat -i interrupt total rate irq0: clk 205278 99 irq1: atkbd0 2 0 irq4: sio0 188 0 irq6: fdc0 1 0 irq7: uhci2 1 0 irq8: rtc 262759 127 irq12: uhci1 puc0 1194 0 irq13: npx0 1 0 irq14: ata0 1724 0 irq15: vr0 ata1 4274 2 Total 475422 231 releng-5-pioneer# and on RELENG_4 # diff -u pucdata.c orig/pucdata.c --- /usr/src/sys/dev/puc/pucdata.c Thu Sep 9 14:18:56 2004 +++ /usr/src/sys/dev/puc/orig/pucdata.c Thu Sep 9 15:50:14 2004 _at__at_ -803,16 +803,6 _at__at_ { PUC_PORT_TYPE_COM, 0x10, 0x00, COM_FREQ }, }, }, - -/* { 0x0000151f, "SmartLink 5634PCV SurfRider", 0x10 }, */ - /* KDW/GE SurfRider */ - { "SmartLink 5634PCV SurfRider", - { 0x151f, 0x0000, 0, 0 }, - { 0xffff, 0xffff, 0, 0 }, - { - { PUC_PORT_TYPE_COM, 0x10, 0x00, COM_FREQ }, - }, - }, /* Actiontec 56K PCI Master */ { "Actiontec 56K PCI Master", --- /usr/src/sys/isa/orig/sio.c Thu Sep 9 15:51:47 2004 +++ /usr/src/sys/isa/sio.c Thu Sep 9 14:19:27 2004 _at__at_ -602,7 +602,8 _at__at_ { 0x048011c1, "Lucent kermit based PCI Modem", 0x14 }, { 0x95211415, "Oxford Semiconductor PCI Dual Port Serial", 0x10 }, { 0x7101135e, "SeaLevel Ultra 530.PCI Single Port Serial", 0x18 }, - { 0x0000151f, "SmartLink 5634PCV SurfRider", 0x10 }, +/* next line removed 2004/09/08 by KDW */ +/* { 0x0000151f, "SmartLink 5634PCV SurfRider", 0x10 }, */ { 0x98459710, "Netmos Nm9845 PCI Bridge with Dual UART", 0x10 }, { 0x00000000, NULL, 0 } }; And the boot -v diffs.
