The BUG trace points very firmly at the ATA code, but your report attributes the crash to the PPPOE code. How can this be? Perhaps the PPPOE code is scribbling on memory which the ata code uses. If you have more oops traces then it would be useful for us to see them please. You could attach them to the bugzilla report and then let us know via reply-to-all to this email, thanks. > ReportedBy: wm666@xxxxxxx > Regression: No > > > Created an attachment (id=46712) > --> (https://bugzilla.kernel.org/attachment.cgi?id=46712) > Screenshot > > uname -a > Linux server 2.6.36-gentoo-r5-sfireman #1 SMP Sun Feb 6 17:34:43 MSK 2011 > x86_64 Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz GenuineIntel GNU/Linux > > lsmod > xt_CLASSIFY 877 24 > sch_sfq 5791 4 > sch_htb 14250 1 > xt_limit 1830 2 > xt_state 1143 5 > ipt_addrtype 1865 0 > xt_DSCP 2059 0 > xt_dscp 1579 0 > xt_string 1211 0 > xt_owner 1063 0 > xt_NFQUEUE 1565 0 > xt_multiport 1702 6 > xt_mark 1093 0 > xt_iprange 1456 0 > xt_hashlimit 5797 0 > xt_conntrack 2551 0 > xt_connmark 1629 0 > scsi_wait_scan 679 0 > > lspci > 00:00.0 Host bridge: Intel Corporation 82P965/G965 Memory Controller Hub (rev > 02) > 00:01.0 PCI bridge: Intel Corporation 82P965/G965 PCI Express Root Port (rev > 02) > 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 > (rev 02) > 00:1c.5 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 6 > (rev 02) > 00:1d.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI > Controller #1 (rev 02) > 00:1d.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI > Controller #2 (rev 02) > 00:1d.2 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI > Controller #3 (rev 02) > 00:1d.3 USB Controller: Intel Corporation Device 2833 (rev 02) > 00:1d.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI > Controller #1 (rev 02) > 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev f2) > 00:1f.0 ISA bridge: Intel Corporation 82801HB/HR (ICH8/R) LPC Interface > Controller (rev 02) > 00:1f.2 SATA controller: Intel Corporation 82801HR/HO/HH (ICH8R/DO/DH) 6 port > SATA AHCI Controller (rev 02) > 00:1f.3 SMBus: Intel Corporation 82801H (ICH8 Family) SMBus Controller (rev 02) > 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E > Gigabit Ethernet Controller (rev 12) > 03:00.0 VGA compatible controller: nVidia Corporation Device 10c3 (rev a2) > 03:00.1 Audio device: nVidia Corporation Device 0be3 (rev a1) > 04:00.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) > 04:02.0 Ethernet controller: D-Link System Inc DGE-530T Gigabit Ethernet > Adapter (rev 11) (rev 11) > 04:04.0 Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit > Ethernet Controller (rev 14) > > kernel bug at /arch/x86/kernel/pci-nommu.c > > how to reproduce: > I use pppoe(pppd with compiled in kernel module for pppoe) > gentoo /etc/conf.d/net > > #HOME DOMAIN NAME > dns_domain_lo="home" > > #LAN > config_eth0=( "192.168.10.1 netmask 255.255.255.0 brd 192.168.10.255" ) > > #WIFI > config_eth1=( "192.168.0.2 netmask 255.255.255.0 brd 192.168.0.255" ) > > #ADSL > config_eth2=( "192.168.1.2 netmask 255.255.255.0 brd 192.168.1.255" ) > > #ADSL Primary > config_ppp0=( > "ppp" > "192.168.1.254" #ALIAS > ) > link_ppp0="eth2" > plugins_ppp0=( "pppoe" ) > username_ppp0='sfireman' > password_ppp0='zpres9' > pppd_ppp0=( > "noauth" > "defaultroute" > "usepeerdns" > "holdoff 3" > "child-timeout 60" > "lcp-echo-interval 15" > "lcp-echo-failure 3" > noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp > ) > > depend_ppp0() { > need net.eth2 > } > > #ADSL Statistic only > config_ppp1=( "ppp" ) > link_ppp1="eth2" > plugins_ppp1=( "pppoe" ) > username_ppp1='stat' > password_ppp1='stat' > pppd_ppp1=( > "noauth" > "defaultroute" > "usepeerdns" > "holdoff 3" > "child-timeout 60" > "lcp-echo-interval 15" > "lcp-echo-failure 3" > noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp > ) > > depend_ppp1() { > need net.eth2 > } > > do.: > /etc/init.d/net.ppp0 start > /etc/init.d/net.ppp1 start > > so. bug causes by starting second ppp link, if first already present. > > Bumps! :( > It's reproduces 100%. > But stack traces is different. > Please, fix it. > > P.S. sorry for my ugly english :) -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
