Hi Aron, Given the 5.4 schedule and resource constraints here, and since this doesn't appear to be a regression, I'm going to propose this for 5.5. If you come up with a patch in the next week, we could maybe squeak it in, but unlikely. Thanks for the good description. Denise Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. |
Description of problem: Updated from RHEL5.4 alpha to beta using yum. Yes I realize this isn't supported but it serves to demonstrate a bug in grubby. I originally had two config stanzas in grub.conf: title Red Hat Enterprise Linux Server (2.6.18-152.el5xen) root (hd0,1) kernel /xen.gz-2.6.18-152.el5 com2=115200 console=com2 module /vmlinuz-2.6.18-152.el5xen ro root=/dev/vg0/rhel5.4 console=ttyS0,115200 module /initrd-2.6.18-152.el5xen.img savedefault title Red Hat Enterprise Linux Server-base (2.6.18-152.el5) root (hd0,1) kernel /vmlinuz-2.6.18-152.el5 ro root=/dev/vg0/rhel5.4 console=ttyS1,115200 initrd /initrd-2.6.18-152.el5.img savedefault The yum upgrade prepended the following two, which is correct: title Red Hat Enterprise Linux Server (2.6.18-155.el5xen) root (hd0,1) kernel /xen.gz-2.6.18-155.el5 com2=115200 console=com2 module /vmlinuz-2.6.18-155.el5xen ro root=/dev/vg0/rhel5.4 console=ttyS0,115200 module /initrd-2.6.18-155.el5xen.img savedefault title Red Hat Enterprise Linux Server (2.6.18-155.el5) root (hd0,1) kernel /vmlinuz-2.6.18-155.el5 ro root=/dev/vg0/rhel5.4 console=ttyS0,115200 initrd /initrd-2.6.18-155.el5.img savedefault The problem here is the difference in the serial console lines: module /vmlinuz-2.6.18-152.el5xen ro root=/dev/vg0/rhel5.4 console=ttyS0,115200 kernel /vmlinuz-2.6.18-152.el5 ro root=/dev/vg0/rhel5.4 console=ttyS1,115200 module /vmlinuz-2.6.18-155.el5xen ro root=/dev/vg0/rhel5.4 console=ttyS0,115200 kernel /vmlinuz-2.6.18-155.el5 ro root=/dev/vg0/rhel5.4 console=ttyS0,115200 Note that in the non-Xen case, the 152.el5 kernel has console=ttyS1,115200 and the 155.el5 kernel has console=ttyS0,115200. Grubby seems to have copied the config from 152.el5xen to 155.el5, which leaves the serial console inoperable. This results in extra reboots and manual edits to get things working right. Version-Release number of selected component (if applicable): RHEL 5.4 beta mkinitrd-5.1.19.6-54.x86_64 kernel-2.6.18-152.el5.x86_64 kernel-2.6.18-155.el5.x86_64 Expected results: - kernel /vmlinuz-2.6.18-155.el5 ro root=/dev/vg0/rhel5.4 console=ttyS0,115200 + kernel /vmlinuz-2.6.18-155.el5 ro root=/dev/vg0/rhel5.4 console=ttyS1,115200 Additional info: (confession) I (re)wrote the grubby code related to this a couple releases ago, so I'm somewhat responsible. If I can find time to look into the bug, I will.
