  • List-id: Xen developer discussion <xen-devel.lists.xensource.com>

I've read the posts where the other users have been reporting Dell
boxes hanging.  I can readily reproduce the symtom, and hopefully
provide some extra info.

This is for a Xen project for work.  I have it running on a
development box with different hardware with no problems whatsoever. 
However, for the rollout stage, Dell 2850's are to be used w/ the PERC
4e/Di controller (new megaraid driver).

I've tried xen-2.0-testing, 2.0.6 and 2.0.4 (all compiled from source), and
the boxes "lock up" exactly the same way.  Basically, I (re)boot the
box to the 2.6.11.10-xen0 (or 2.6.11.12-xen0) kernel, ssh in, issue
`vgscan; vgchange -ay; mkfs.ext3 /dev/lvm/device` and it'll proceed
briefly then appear to be completely locked up (network dies),
keyboard doesn't respond (can't toggle caps lock), etc.

However, one time I just decided to let it sit there (over lunch) and
upon returning, was able to log in using the console.  Examining the
dmesg, I noticed:

Jul 18 12:36:18 xen0 megaraid: aborting-17662 cmd=2a <c=2 t=0 l=0>
Jul 18 12:36:18 xen0 megaraid abort: scsi cmd:17662, do now own

repeated over and over again.

I tried disabling USB (via nousb boot param), and it locks up exactly
the same way.

Booting the normal vmlinuz-2.6.12-gentoo-r4 kernel and performing the
same steps do not lock up the box.

Please let me know if there's any additional info you'd like me to
provide or anything else you'd like me to try.  If this issue cannot
be resolved, then I'll obviously have to scrap the Xen project.  And
having played with UMLs, I'd rather not have to touch that if possible
at all.

Thanks,
Shane
