PROBLEM: Linux-2.6.6 with dm-crypt hangs on SMP boxes
From: Dr. Ernst Molitor
Date: Fri May 21 2004 - 19:42:25 EST
Dear Linux gurus,
please forgive me for being vague - I'd rather be more specific if I
only could, and I'd readily try and follow any procedure you might
suggest to arrive at further information about the problem...
[1.] Linux-2.6.6 caused full halts on two SMP boxes.
[2.] I've been using Linux-2.4.20 with cryptoloop/cryptoapi for 156
days uptime; on two boxes, I have installed 2.6.6-rc3-bk5 (one box) and
2.6.6-bk5 (the other one), with dm-crypt on the partitions created with
cryptoloop/cryptoapi. Both boxes ran like a charm, but both of them
repeatedly came to a halt (no screen, no network connectivity, no
reaction to keyboard or mouse activity: Need for hard reset) repeatedly.
[3.] dm-crypt, loop device (maybe other things).
In kern.log on the box with 2.6.6-bk5, I found the line
Incorrect TSC synchronization on an SMP system (see dmesg).
with the 2.6.6 kernels, with 2.4.20, the message was
checking TSC synchronization across CPUs: passed.
[4.] 2.6.6, 2.6.6-bk5
[5.] sorry, no Oops available
