Issue tracker opened for this. 140420 This has been committed for the beta. in 2.6.18-71.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 Red Hat is tracking the patch for this issue under the following BZ, which is confidential to another party. 227614. Please make sure you scan the changelog for the beta for this reference BZ. Looks like information is not properly flowing from IT to BZ. Here's the latest
entry in the IT:
Event posted 03-12-2008 01:54pm EDT by sandy.garza
Internal Status set to 'Waiting on Support'
Retest failed with Kernel 82.el5.
Status set to: Waiting on Tech
Um, we need a lot more information than that. How does it fail? Any console logs, anything from dmesg, xm dmesg, etc. etc.? Chris Lalancette Created attachment 298310 [details]
Serial Output Using dzickus kernel
This is from the xen -75 kernel on dzickus. This is the output when the kernel
boots to xen via the serial port. I ran with the beta release of the kernel
-85 with similar results.

SOS report of DL580G5 with 256GB
This is using RHEL 5.1 x64 base media only.
Sandy/Jeff, Can you please describe exactly what you're seeing with the new kernel? I believe we're seeing something different. Under -53.el5, we saw the following in 'xm dmesg': (XEN) WARNING: Only the first 166 GB of the physical memory map can be accessed (XEN) by compatibility mode guests. Truncating the memory map... ... (XEN) System RAM: 169212MB (173274008kB) However with -75.el5, we don't see the warning, and it looks like the system has far less memory in it. Can you attach a sosreport from the system running -75.el5 (or better yet, Beta Snapshot 1)? Thanks! -David Internal Status set to 'Waiting on Customer' Status set to: Waiting on Client This event sent from IssueTracker by dwa issue 140420 When I run using Snapshot 1 the system will get mostly through the boot process... (XEN) Xen is relinquishing VGA console I then lose output to my monitor (above is the last thing displayed on the screen). The serial output I provided is once the system gets to this point, I then log in via a serial cable. The system is in the hypervisor kernel. Am I stuck here or is there a way to get to bash? The system shows 256GB using the RHEL 5.2 Snapshot 3. Alt sysrq M shows all memory. /proc/meminfo shows all memory. HTS memory test passes as well. fixed in kernel-2.6.18-87.el5 (Snapshot 3) An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2008-0314.html |
