The only way to return to a normal state is by reboot. But also the reboot fails (it hangs somewhere, I cannot see the console. I'm using nvidia's video driver and have black console as soon as X starts - I can eventually set the nv or vesa driver in xorg.conf and then see). The worst part is it hangs during shutdown before unmounting HDDs. alt+ctrl+del nor sysrq does not work so I need to hard boot (power off). (Therefore I set this bug as critical, otherwise it can be major) I have no idea what causes it. Maybe network? Time in /var/log/messages shows only dhcpd doing its stuff + knetworkmanager somewhat appears on the top list. It hangs on both wlan or lan I searched for a while. Some guy have similar problem with a Clevo notebook with very similar specs. I had no such problem with previous suse (11.0) Any ideas? My ideas for now can be to try these : - use for a while only the vesa/nv driver - install vanilla kernel - download & install - disable dhcp daemon (easiest I think) Here is top of the top processes: top - 22:35:21 up 1 day, 4:05, 7 users, load average: 1.66, 1.76, 1.52 Tasks: 142 total, 3 running, 139 sleeping, 0 stopped, 0 zombie Cpu0 : 2.0%us, 6.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 92.0%si, 0.0%st Cpu1 : 4.0%us, 0.0%sy, 0.3%ni, 95.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 4088564k total, 3940616k used, 147948k free, 66132k buffers Swap: 4409800k total, 28k used, 4409772k free, 3204660k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4 root 15 -5 0 0 0 R 99 0.0 24:24.67 ksoftirqd/0 3049 root 20 0 360m 69m 9772 S 4 1.7 31:08.22 X 9720 micho 39 19 128m 47m 14m S 4 1.2 14:14.83 operapluginwrap 9628 micho 20 0 511m 382m 17m S 2 9.6 12:52.75 opera 10710 micho 20 0 156m 56m 29m S 2 1.4 11:58.14 amarokapp 3853 micho 20 0 35884 13m 8840 S 1 0.3 2:55.25 knetworkmanager 8838 root 15 -5 0 0 0 S 1 0.0 0:00.96 events/1 3984 micho 20 0 37716 16m 10m R 0 0.4 1:51.73 konsole 11588 root 20 0 99112 57m 24m S 0 1.4 0:51.00 y2base 1 root 20 0 1008 356 308 S 0 0.0 0:01.20 init 2 root 15 -5 0 0 0 S 0 0.0 0:00.00 kthreadd 3 root RT -5 0 0 0 S 0 0.0 0:00.14 migration/0 7 root 15 -5 0 0 0 S 0 0.0 0:05.14 events/0 /var/log/messages around the fatal time (I think it occured somewhere after the "MARK"): Jan 9 21:46:30 linux-6vsc dhclient: DHCPREQUEST on eth0 to 192.168.1.1 port 67 Jan 9 21:46:31 linux-6vsc dhclient: DHCPACK from 192.168.1.1 Jan 9 21:46:31 linux-6vsc dhclient: bound to 192.168.1.3 -- renewal in 1625 seconds.
