I don't know why I didn't think of this at first, but I have another identical machine that I upgraded at the same time that doesn't have the problem. Here's a diff between their .configs - albarino is the one having trouble. Maybe CONFIG_PACKET_MMAP? If someone can point me at a likely config option to change I'll boot a new kernel for the next backup run Friday night. --- config-albarino 2004-10-28 18:31:57.000000000 -0400 +++ config-airen 2004-10-28 18:40:35.000000000 -0400 @@ -1,7 +1,7 @@ # # Automatically generated make config: don't edit # Linux kernel version: 2.6.9 -# Thu Oct 28 18:31:48 2004 +# Thu Oct 28 18:40:27 2004 # CONFIG_X86=y CONFIG_MMU=y @@ -168,7 +168,7 @@ CONFIG_PCI_BIOS=y CONFIG_PCI_DIRECT=y CONFIG_PCI_MMCONFIG=y -CONFIG_PCI_LEGACY_PROC=y +# CONFIG_PCI_LEGACY_PROC is not set CONFIG_PCI_NAMES=y CONFIG_ISA=y # CONFIG_EISA is not set @@ -252,7 +252,7 @@ CONFIG_BLK_DEV_RAM=y CONFIG_BLK_DEV_RAM_SIZE=4096 CONFIG_BLK_DEV_INITRD=y -CONFIG_LBD=y +# CONFIG_LBD is not set # # ATA/ATAPI/MFM/RLL support @@ -283,7 +283,7 @@ CONFIG_BLK_DEV_IDEPCI=y CONFIG_IDEPCI_SHARE_IRQ=y # CONFIG_BLK_DEV_OFFBOARD is not set -CONFIG_BLK_DEV_GENERIC=y +# CONFIG_BLK_DEV_GENERIC is not set # CONFIG_BLK_DEV_OPTI621 is not set # CONFIG_BLK_DEV_RZ1000 is not set CONFIG_BLK_DEV_IDEDMA_PCI=y @@ -437,7 +437,7 @@ # Networking options # CONFIG_PACKET=y -# CONFIG_PACKET_MMAP is not set +CONFIG_PACKET_MMAP=y # CONFIG_NETLINK_DEV is not set CONFIG_UNIX=y # CONFIG_NET_KEY is not set @@ -453,58 +453,8 @@ # CONFIG_INET_ESP is not set # CONFIG_INET_IPCOMP is not set # CONFIG_INET_TUNNEL is not set - -# -# IP: Virtual Server Configuration -# -# CONFIG_IP_VS is not set # CONFIG_IPV6 is not set -CONFIG_NETFILTER=y -# CONFIG_NETFILTER_DEBUG is not set - -# -# IP: Netfilter Configuration -# -CONFIG_IP_NF_CONNTRACK=y -# CONFIG_IP_NF_CT_ACCT is not set -# CONFIG_IP_NF_CT_PROTO_SCTP is not set -CONFIG_IP_NF_FTP=y -# CONFIG_IP_NF_IRC is not set -# CONFIG_IP_NF_TFTP is not set -CONFIG_IP_NF_AMANDA=y -# CONFIG_IP_NF_QUEUE is not set -CONFIG_IP_NF_IPTABLES=y -# CONFIG_IP_NF_MATCH_LIMIT is not set -CONFIG_IP_NF_MATCH_IPRANGE=y -# CONFIG_IP_NF_MATCH_MAC is not set -# CONFIG_IP_NF_MATCH_PKTTYPE is not set -# CONFIG_IP_NF_MATCH_MARK is not set -# CONFIG_IP_NF_MATCH_MULTIPORT is not set -# CONFIG_IP_NF_MATCH_TOS is not set -# CONFIG_IP_NF_MATCH_RECENT is not set -# CONFIG_IP_NF_MATCH_ECN is not set -# CONFIG_IP_NF_MATCH_DSCP is not set -# CONFIG_IP_NF_MATCH_AH_ESP is not set -# CONFIG_IP_NF_MATCH_LENGTH is not set -# CONFIG_IP_NF_MATCH_TTL is not set -# CONFIG_IP_NF_MATCH_TCPMSS is not set -# CONFIG_IP_NF_MATCH_HELPER is not set -CONFIG_IP_NF_MATCH_STATE=y -# CONFIG_IP_NF_MATCH_CONNTRACK is not set -# CONFIG_IP_NF_MATCH_OWNER is not set -# CONFIG_IP_NF_MATCH_ADDRTYPE is not set -# CONFIG_IP_NF_MATCH_REALM is not set -# CONFIG_IP_NF_MATCH_SCTP is not set -# CONFIG_IP_NF_MATCH_COMMENT is not set -CONFIG_IP_NF_FILTER=y -# CONFIG_IP_NF_TARGET_REJECT is not set -CONFIG_IP_NF_TARGET_LOG=y -# CONFIG_IP_NF_TARGET_ULOG is not set -# CONFIG_IP_NF_TARGET_TCPMSS is not set -# CONFIG_IP_NF_NAT is not set -# CONFIG_IP_NF_MANGLE is not set -# CONFIG_IP_NF_RAW is not set -# CONFIG_IP_NF_ARPTABLES is not set +# CONFIG_NETFILTER is not set # # SCTP Configuration (EXPERIMENTAL) @@ -660,8 +610,8 @@ # CONFIG_INPUT_MOUSEDEV=y CONFIG_INPUT_MOUSEDEV_PSAUX=y -CONFIG_INPUT_MOUSEDEV_SCREEN_X=1280 -CONFIG_INPUT_MOUSEDEV_SCREEN_Y=1024 +CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024 +CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768 # CONFIG_INPUT_JOYDEV is not set # CONFIG_INPUT_TSDEV is not set # CONFIG_INPUT_EVDEV is not set @@ -719,8 +669,7 @@ CONFIG_UNIX98_PTYS=y CONFIG_LEGACY_PTYS=y CONFIG_LEGACY_PTY_COUNT=256 -CONFIG_PRINTER=y -# CONFIG_LP_CONSOLE is not set +# CONFIG_PRINTER is not set # CONFIG_PPDEV is not set # CONFIG_TIPAR is not set @@ -886,8 +835,8 @@ # USB Host Controller Drivers # CONFIG_USB_EHCI_HCD=y -# CONFIG_USB_EHCI_SPLIT_ISO is not set -# CONFIG_USB_EHCI_ROOT_HUB_TT is not set +CONFIG_USB_EHCI_SPLIT_ISO=y +CONFIG_USB_EHCI_ROOT_HUB_TT=y # CONFIG_USB_OHCI_HCD is not set CONFIG_USB_UHCI_HCD=y @@ -1056,13 +1005,10 @@ CONFIG_NFS_V3=y # CONFIG_NFS_V4 is not set # CONFIG_NFS_DIRECTIO is not set -CONFIG_NFSD=y -CONFIG_NFSD_V3=y -# CONFIG_NFSD_V4 is not set -# CONFIG_NFSD_TCP is not set +# CONFIG_NFSD is not set CONFIG_LOCKD=y CONFIG_LOCKD_V4=y -CONFIG_EXPORTFS=y +# CONFIG_EXPORTFS is not set CONFIG_SUNRPC=y # CONFIG_RPCSEC_GSS_KRB5 is not set # CONFIG_RPCSEC_GSS_SPKM3 is not set @@ -1083,7 +1029,7 @@ # CONFIG_NLS=y CONFIG_NLS_DEFAULT="iso8859-1" -CONFIG_NLS_CODEPAGE_437=y +# CONFIG_NLS_CODEPAGE_437 is not set # CONFIG_NLS_CODEPAGE_737 is not set # CONFIG_NLS_CODEPAGE_775 is not set # CONFIG_NLS_CODEPAGE_850 is not set @@ -1107,7 +1053,7 @@ # CONFIG_NLS_CODEPAGE_1250 is not set # CONFIG_NLS_CODEPAGE_1251 is not set # CONFIG_NLS_ASCII is not set -CONFIG_NLS_ISO8859_1=y +# CONFIG_NLS_ISO8859_1 is not set # CONFIG_NLS_ISO8859_2 is not set # CONFIG_NLS_ISO8859_3 is not set # CONFIG_NLS_ISO8859_4 is not set - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
