Sorry to report this as an r4 bug, although it's interesting to note that the 1.12.4 baselayout did NOT cause this problem in reiserfs3.6 Mine was doubtlessly a Reiser4 bug, as it resulted in either an oops or a panic, I'm not sure which. I think it was an oops, and after that oops, the disk is inaccessible. Since it's a root FS, this is a problem! The init scripts should not be able to cause this, no matter how buggy they are. That's good to know...I guess :) I haven't done this already, because everything works now, and no one's asked me to yet. I find this curious, don't you? I'm wondering if kernel preemption settings and anticipatory read ahead settings could play a role? Mine are CONFIG_PREEMPT=y and CONFIG_DEFAULT_IOSCHED=CFQ. One other thing of note is that my kernel has Jens Axboe's iosched-rollup-2.6.17.4-2 patch. My reiser4 patch is 2.6.17-3. The iosched patch removed a lot of dma messages in the kernel log (not disk errors). Anyway, whatever changed in my downgraded baselayout, at least it's not causing reiser4 to hiccup. Curious problem in that it only occurs immediately after a shutdown, not after the error and a reboot from a maintenance prompt. -- Peter + Do not reply to this email, it is a spam trap and not monitored.

You can use either serial or network console to catch kernel output. Well, the output is from the gentoo rc script and from the imported functions.sh script. It showed two segfaults. It occured afaikt when the dmcrypt addon is called. It uses the start-stop-daemon program. I tried taking a photo of it, but it was blurry and the flash obscured it. I backtracked all the way from the errant baselayout and until 1.11.15-r3 none of the 1.12 series of baselayouts worked. Too bad I can't get gpm to run otherwise I could capture the output. However, the only output are lines from the script with uninitialized variables -- basically the source of the scripts.

As you can see, there are no panics or dumps and it appears that for whatever reason, the init scripts just cannot continue. However, the reboot (ctrl-d), the scripts execute fine.

My version of baselayout has that fix, but that does not appear to be the problem. I think it has more specifically to do with the way the remount option is affecting the reiser4 fs.

This looks like you have problems on startup. Would you, please, describe the sequence of operations which leads to the problem with more details. I should have written that it occurs always after a normal shutdown or reboot. On initial startup, the error occurs. Then, after CTRL-D, the system reboots and all is fine. Then, after the day, normal shutdown, then abnormal startup. Some more information, I looked at the output from the final mount -v -n -o remont,ro / command, it appears perfectly normal.

reiser4: mount -o remount,ro / causes error on reboot
Using: gentoo
kernel 2.6.17.11 with beyond patchset
reiser patch 2.6.17-3
reiser4progs 1.0.5
At the end of the gentoo shutdown script is a short function which
remounts / as ro.
sync; sync
sleep 1
.
# ${x} = /
mount -n -o remount,ro ${x} /dev/null
On reboot or after a poweroff, root does not mount properly, and after
some modules are loaded, there are segfaults when running init scripts.
The init scripts prompts for the root password for maintenance. Simply
typing exit forces an unmount of / and a reboot.
After this, everything is normal. On a normal shutdown, this error cycle
begins anew. Something has changed in the gentoo shutdown sequence as this
error is new to my system. However, gentoo does not support reiser4 as it
is experimental. I wanted to report this.
Remount is required since with the halt script running, the root cannot be
unmounted. After halt.sh, reboot -idpk is called or shutdown.
