Bug#684293: root cause of mount hang in installer [kernel bug]
On Thu 09 Aug 2012 at 13:29:20 +0100, Brian Potkin wrote: Either before or just after selecting a language and configuring the keyboard I executed 'mountmedia' and 'mountmedia driver'. Everything seems to go well, with extended partitions being detected and attempted to be mounted. After selecting cdrom-detect mountmedia stops at the first extended partition it finds. This does not happen with the alpha-1 image and I have no explanation why detecting and mounting the CD-ROM should trigger this behaviour. To follow up on this: The two lines in mountmedia mount $1 -tauto $MNT || true and mount $1 -tauto $MNT can be altered to look explicitly for vfat partitions with -tvfat. Detection and loading of missing firmware then takes place as we would expect. I offer this as an observation, not as a solution, because I'm unsure how it would affect d-i as a whole. After detecting and mounting the CD-ROM the iso9660 filesystem is shown in /proc/filesystems and my thinking is that this may be the cause of the present problem. The installation proceeds as usual if, after loading the installer components. /cdrom is unmounted and the isofs module unloaded from the kernel. When mountmedia hangs it appears to be because -tauto tests for an iso9660 filesystem first and fails with an extended partition. The lsmod output shows two processes using the isofs module. I assume mountmedia cannot go on to look for other partition types until the second process has completed. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe.

Bug#684293: root cause of mount hang in installer [kernel bug]
Quoting M H (mh000...@yahoo.com): After some googling I found out that the root cause of the recent mount problems with extended partitions (maybe also mounting disks like sda) are related to the infinite loop kernel bug in __getblk_slow. (see the explanation: https://patchwork.kernel.org/patch/1189121/) The affected debian kernels should get fixed with the patch offered in kernel 3.2.24 (http://lwn.net/Articles/508225/).

Is it me or do both these URL return 404? Quickly tested both of them a minute ago. They worked for me. OK, reassigning to the Linux kernel. To Debian Kernel team: this bug has been revealed in D-I beta1. Any attempt to mount an extended partition (which is done in both mountmedia and iso-scan) loops forever and D-I appears to be hanged. This happens for instance each time D-I looks for missing firmware on existing devices. We had several bug reports about this. mountmedia has been fixed (more with a workaround than a real fix) but iso-scan is still affected. So, it seems that the patch described above is highly wished for wheezy. It would be great to have it before D-I beta2, indeed. For that reason, I set the bug's severity to critical (breaks unrelated packages). signature.asc Description: Digital signature

Thanks for the investigation and your care looking out for the root cause of this. This bug, and probably all other hang bugs, should be reassign to the kernelpackage. Before doing so, I'm awaiting for input from a Kerneal Team person. Thank you for pursuing this lead. Meanwhile, may I relate the result of what happens for me with the beta-1 image. Either before or just after selecting a language and configuring the keyboard I executed 'mountmedia' and 'mountmedia driver'. Everything seems to go well, with extended partitions being detected and attempted to be mounted. After selecting cdrom-detect mountmedia stops at the first extended partition it finds. This does not happen with the alpha-1 image and I have no explanation why detecting and mounting the CD-ROM should trigger this behaviour. A log is attached.
