105414 2005-09-09 11:39 0000 udevstart from udev-068 triggers a kernel panic 2005-12-05 11:07:20 0000 1 1 1 Unclassified Gentoo Linux Core system unspecified HPPA Linux RESOLVED FIXED P2 critical --- 1 jer@gentoo.org hppa@gentoo.org jer@gentoo.org 2005-09-09 11:39:20 0000 After merging sys-fs/udev-068, running udevstart on a B160L during the same 'boot session' caused a kernel panic ("not syncing") without any other error mentioned. A reboot did not help at all, probably for the same reason (udevstart causing a kernel panic), this time while init was minding the contents of /dev. A reboot with the gentoo=nodevfs did give some warnings, but at least allowed me to safely remerge udev-058. The problem didn't occur again after that, and running udevstart 'manually' didn't give any problems with 058. Reproducible: Always Steps to Reproduce: 1. Upgrade to (oddly marked stable for HPPA) sys-fs/udev-068. 2. Reboot or run udevstart. Actual Results: Panic! Expected Results: No panic.

I'll try hppa-sources-2.6.13_p1 (~hppa) as it is newer than my current (very stable) 2.6.12.4-pa2 (hppa). jer@gentoo.org 2005-09-09 15:22:20 0000 hppa-sources-2.6.13_p1 went exactly the same: doing 'udevstart' caused a kernel panic, and rebooting caused a kernel panic. Then rebooting with gentoo=noudev (as earlier -- consider this a correction of my earlier report of using gentoo=nodevfs) brought the system up properly. jer@gentoo.org 2005-09-09 15:26:25 0000 (In reply to comment #3) > Then rebooting with gentoo=noudev > (as earlier -- consider this a correction of my earlier report of using > gentoo=nodevfs) brought the system up properly. Addendum: Then running udevstart again does *not* trigger a kernel panic. jer@gentoo.org 2005-10-11 22:57:40 0000 Created an attachment (id=70436) What netconsole managed to send... This dmesg log (if you will) was triggered after an upgrade to sys-fs/udev-068-r1 (current stable for hppa) by a subsequent run of 'udevstart'. gmsoft@gentoo.org 2005-10-16 12:48:19 0000 This is caused by "vol_id --export /dev/.tmp-43-0" which udevstart uses to populate /dev. When it reads the block device 43 0, there is a kernel panic. If you set CONFIG_BLK_DEV_NBD=n, the problem goes away. This is then a kernel problem. I'll forward this issue to pa kernel guys. gmsoft@gentoo.org 2005-12-05 11:07:20 0000 Fixed kernel in cvs. 70436 2005-10-11 22:57 0000 What netconsole managed to send... hpvis_udev-068-r1-panic
