Re: 2.5.9 kreiserfsd and sync hung in D state

[rwhron]

This may be a generic 2.5.9 on this hardware issue.  
dbench on ext2 also hung in D state.  Haven't got a 
sysrq-T yet, but the reiserfs list isn't the right place
for this problem it seems.

Thanks for the pointers.

That basically is the test.

Will post sysrq-T when I find out how.

No preempt.  It has highmem.  It also has tagged queueing

2.5.9 kreiserfsd and sync hung in D state

[rwhron]

I didn't notice any of the 2.5.8.pending fixes in 
ChangeLog-2.5.9, and I haven't tried them with 2.5.9 yet.

Linux 2.5.9 without any patches.

Uninteruptable sleep created by:
mkreiserfs /dev/sdc2
mount -t reiserfs -o defaults,noatime /dev/sdc2 /fs2
cpio -pdm filenames |  /fs2
sync			# this is what has hung

ps aux
USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND
root      1113  0.0  0.0     0    0 ?        DW   03:49   0:00 [kreiserfsd]
root      1265  0.0  0.0  1636  488 ttyp0    D    03:52   0:00 sync

A similar mke2fs;mount;cpio;sync on ext2 did not hang.

The SCSI drivers for this machine were recently fixed in 2.5.9.  
They may not be bulletproof yet.

I would like to get reiserfs on 2.5.9 working on this machine.
Any suggestions appreciated.

A sysrq-t would probably help.

Sorry? You mean you piped cpio output into mountpoint? And it worked?

> sync			# this is what has hung

Can you see where it hung? (alt-sysrq-T, if you have sysrq enabled).

I am going to try reproducing.
