Hi dear Xen users, We experienced kernel panic while acessing / filesystem with an HP DL-380 G3. cciss support is well activated , it is running with G2, G4 and G5 but not with G3. We tried to build from source, binary from Xen comunity and binary for RedHat, there''s always same symptome. We tried Xen 3.01, 3.02, 3.05, Xen 3.1. HP CCISS is discovered but not the partition table, so, we can''t mount /dev/cciss/c0d0p1 for / . Hardware is product: ProLiant DL380 G3 description: RAID bus controller product: Smart Array 5i/532 vendor: Compaq Computer Corporation Board ID: 0x40800e11 As I could read here http://hcl.xensource.com/?show=6171&showtype=driver device id b178 my controlleur should be supported with Xen 3.2. But where can i download soure code ? it should be avalibable in Xen 3.1, is there a special configuration to apply ? Should CONFIG_BLK_CPQ_CISS_DA=y be unsufficient in my .config ? Thanks a lot, Bye, Daffy _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

[Xen-users] Re: Kernel Panic from dom0 with smart array 5i

Solution was to remove acpi=off from the grub line. We used this options to enable more than 4 Go of RAM on other hardware. Now, with Xen 3.2.0 (really a last checkout from mercurial, Xen 3.2.1 rc1 , just a few hours before the official announce on xen-devel list), Xen starts on HP DL-380 G3 dual Xeon 2.8 GHz and 6 Gb RAM. dom0 and domU OK. I had to change this on the domU configuration : cpu is now vcpu andd xencons=tty in the append line , console=tty on kernel and module line from the grub.conf are not sufficient now. Then,I made some brindging tests : - NATIVE : bridging eth0 <-> xenbr0 OK with network-bridge - MULTIPLE NATIVE bridges in bridge.conf, KO with network-bridge. OK with our bridge-wrapper, if we do not specified vif number from the command line argument passed to network-bridge. - VLAN : eth0.vlan bridged to xenbr.vlanid OK (need ONBOOT=yes for the ifcfg-bond0.vlanid first or Xen doesn''t initiate vconfig) - BONDING : bond0 bonding on eth0+eth1 , bridged on xenbr0 : OK - BONDING+VLAN : bond0.vlanid (over eth0+eth1) bridged on xenbr.vlanid : KO => Kernel Panic. My interface bond0.vlanid is up and running, but when Xend start, I systematically failed with a kernel panic. Here is some of my call trace : cannot create /proc/net/bonding/<NULL> BUG : unable to handle NULL pointer dereference OOOPS : 0000 #1 EIP : 0061 EIP is at sysfs_remove_group [...] Call trace : show_stack_log_lv show_vg die do_page_fault error_code 0x2b/0x30 bond_destroy_sysfs_entry [bonding] bond_event_changename [bonding] bond_master_netdev_event [bonding] notifier_call_chain dev_change_name dev_ifctl dev_ioctl sock_ioctl vfs_ioctl syscall_call 0x7/0xb EIP sysfs_remove_group 0x57/0xb0 SS ESP 0069 C0997E08 Hum ..... :-( Sould anyone help me ?
