Description Bart Van Assche 2009-08-23 18:04:25 UTC

About one out of three times the system on which I installed a kernel obtained from linux/kernel/git/roland/infiniband.git (for-next branch) hangs during boot. The symptoms if the system hangs during boot are as follows (see also the attached screenshot):
- console tty echo still works -- any keys pressed are echoed on the screen; caps lock works.
- the console switching keys (Alt-F1 / Alt-F2) did not have any effect -- maybe the virtual consoles had not yet been initialized.
- Ethernet interfaces had not yet been brought up: one of the Ethernet interfaces is connected with a crossed cable to another Linux system. That second system had logged the message "kernel: sky2 eth0: Link is down." during shutdown of the first system. But the second system had not yet reported that the first system had brought up its Ethernet interfaces.
- The following message was displayed several times on the console: "ifup-dhcp [...] trap invalid opcode ip:... sp:... error:0 in bash[...]

Kernel command line:
$ cat /proc/cmdline
root=/dev/disk/by-id/ata-ST3160815AS_6RA2TMXQ-part6 resume=/dev/disk/by-id/ata-ST3160815AS_6RA2TMXQ-part5 splash=silent vga=0 edd=off

Note: adding slub_debug=FZPU to the kernel command line did not reveal any extra information. I have not yet been able to reproduce this issue with the parameter slub_debug=FZPU added to the kernel command line.

Comment 6 Bart Van Assche 2009-08-26 06:08:46 UTC

Note: the same system boots fine with the 2.6.30.4 and several older kernels.

Comment 7 Rafael J. Wysocki 2009-09-06 19:53:54 UTC

Can you please test 2.6.31-rc9 too?

Comment 8 Bart Van Assche 2009-09-12 15:32:04 UTC

I have not yet been able to reproduce this issue with the 2.6.31 kernel (final release, not the rc9). Still testing with the latest infiniband.git kernel, which is based on 2.6.31-rc9.

Comment 9 Bart Van Assche 2009-09-19 14:24:40 UTC

Closing as invalid because caused by an unreliable motherboard.
