It doesn't work that way. The developers don't have a problem or it would have been fixed. You are going to need to provide more details and do some investigations yourself to help identify the problem. >Loader on it's own stage easily detects HDD and root partition so I >can just select old kernel and boot up, but I'm not shure how he gain >access to HDD to mfke any conclusion, probably through BIOS interrupts >but it's out of piont. Yes. Until the kernel starts, all I/O is via BIOS. >And for my pity I don't know how to dump demsg without having any >serial connection or usable disk drive, maybe to flash drive, but I >don't know how.

Best suggestion I can offer is to take photographs of the boot messages (you can use scroll-lock to let you scroll back) and post them somewhere. >If you need any aditional info I'll give it all, just ask. What is the SVN revision of a kernel that works? What is the SVN revision of a kernel that fails? Can you please post a verbose dmesg of a successful boot. Can you please post a dmesg of an unsuccessful boot (see above). --=20 Peter Jeremy --r5Pyd7+fXNt84Ff3 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAk0bprEACgkQ/opHv/APuIf5oQCgq24USL9WmdnrSFwDZO+ztRTb 8wMAn1e/aaHTMKlRgHpCRfIUtKh/SnWH =Gc9+ -----END PGP SIGNATURE----- --r5Pyd7+fXNt84Ff3--
