Can you please post full dom0 boot logs, both "xm dmesg" and kernel "dmesg"? Created attachment 146276 [details]
dmesg
this is the dmesg, xm dmesg will follow
both are _before_ the system IO freezes, because I can't access the system
after the oops anymore

There was a nasty bug in 1.3002 which might just be implicated here; can you please try to reproduce with 2.6.18-4.el5? Thanks. sorry for putting the bug to the wrong state! I now updated dom0 to latest webqa kernel (2.6.18-5.el5xen) but still experienced the problem. FYI, in between I also switched the SATA mode in the T60p's BIOS from AHCI to Compatible (using module ata_piix instead of ahci) but the problem still existed, so I switched back to AHCI. I just tried with the latest kernel from webqa, 2.6.18-8.el5xen, still the same behaviour, after downloading several megabytes via ipw3945 in the virtual guest the host looses IRQ #21 and is left unusable. Is there anything I can do to help? It would be helpful to get the _full_ log of the error when it hits. Can you please try to set up serial console or netconsole? For a laptop, serial console likely implies a docking station these days, but netconsole should still work. (You'll need to modprobe netconsole manually; "modinfo netconsole" should show you the required parameters, and you can redirect the output to syslogd on another host. If you set it up once xend is running, you'll need to run it on peth0, not eth0, too.) change QA contact This has been in NEEDINFO for over 2 years. I'm going to close it out for now; if you are still having the problem, and want to pursue the problem, please feel free to re-open. Chris Lalancette |
