----Security_Multipart(Mon_May__4_04_52_04_2009_044)-- Content-Type: Text/Plain; charset=us-ascii Content-Transfer-Encoding: 7bit During upgrading boxes in allbsd.org to RELENG_7_2_0_RELEASE I found one of them could not boot at the loader stage. The error messages issued by the loader after "make installkernel + make installworld + reboot" were the following: |Loading /boot/defaults/loader.conf |/boot/kernel/kernel text=0x7cbd7c data=0xcece0+0x67940 |readin failed | |elf32_loadimage: read failed |/boot/kernel/kernel text=0x7cbd7c data=0xcece0+0x67940 |readin failed | |elf32_loadimage: read failed |Unable to load a kernel! The normal loader prompt was displayed after that and I can enter commands, but neither the kernel nor some old kernels which I confirmed they worked fine got loaded. Then I tried a livefs CDROM, but the same error occurred at the loader stage. So I tried 7.1R CDROM instead, mounted the root file system on the hard drive, and copied a loader binary from 7.1R. It worked with no problem with the RELENG_7_2_0_RELEASE kernel. The motherboard was Supermicro P4DPE (Xeon 2.4GHz x 2, 3GB RAM). The installed version was FreeBSD/i386. I did not narrow down the cause yet due to the time was limited, but it was reproducible and probably hardware-dependent. Replacing the loader binary with the old one worked as a workaround, so I guess there may be a regression around the boot loader. Just a report. -- | Hiroki SATO ----Security_Multipart(Mon_May__4_04_52_04_2009_044)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAkn99eQACgkQTyzT2CeTzy0awQCeKfXVJ4pQlgPv4leN6hQp/JeO y2IAoMSV8hQRGRTCLmEEKy0Xh/LK+pIp =4oUj -----END PGP SIGNATURE----- ----Security_Multipart(Mon_May__4_04_52_04_2009_044)----
