[linux-lvm] 2.4.3-ac{6,7} LVM hang

[linux-lvm] 2.4.3-ac{6,7} LVM hang

[Rik van Riel]

Hi,

2.4.3-ac4 seems to work great on my test box (UP K6-2 with SCSI
disk), but 2.4.3-ac6 and 2.4.3-ac7 hang pretty hard when I try
to access any of the logical volumes on my test box.

The following changelog entry in Linus' changelog suggests me
whom to bother:   ;)
 - Jens Axboe: LVM and loop fixes

regards,

Rik

Hello,

Same here as reported.
restoring lvm.c from 2.4.3 into 2.4.4-pre? "fixes" this. (tested not ac's
kernel)

Greatings,

Jens, I guess we should submit these patches to Alan and Linus
now. This way we'll get a working LVM again.

Waiting for the next official LVM release (and the next set of
bugs) doesn't seem like a very productive way to me ;)

regards,

Rik

Hello Jens,

Yes this fixes it.

I'm running 2.4.4-pre4 with only your patch applied.

Greatings,

sorry i am a bit late on ac releases (ac3 at the moment)
does ac6/7 include lvm 0.9.1beta7, does the problem happen
with stock kernel lvm, wich was b2 afaik, or with lvm patches applied?
in the former case, why bother? b2 is broken anyway.
