 |
|
I have some bad Kernel Panic:
CPU 0: Maschine Check Exception 000000000000004
Bank 4: b200000000000000070f0f
Kernel panic - not syncing: CPU context corrupt
This never happens if i use my PC under normal conditions, but only if i copy some Data from sdc1 to sdb1. Most of the time the PC jst stops working and does not show the Kernel Panic. I use encrypted Filesystem.
I have 3 HDs:
sda1: /boot - ext2
sda2: swap - swap
sda3: /tmp - xfs
sda4: / -xfs
sdb1: /backup (encrypted, xfs)
sdc1: /home (encrypted, xfs)
here my lines from /etc/security/pam_mount.conf.xml
| Code: | <volume user="frieder" fstype="crypt" path="/dev/sdc1" mountpoint="/home" options="noatime" />
<volume user="frieder" fstype="crypt" path="/dev/sdb1" mountpoint="/backup" options="noatime" /> |
luksDump Information:
| Code: |
todesstern # cryptsetup luksDump /dev/sdb1
LUKS header information for /dev/sdb1
Version: 1
Cipher name: aes
Cipher mode: lrw-benbi
Hash spec: sha1
Payload offset: 2056
MK bits: 256 |
| Code: |
todesstern # cryptsetup luksDump /dev/sdc1
LUKS header information for /dev/sdc1

I am using gentoo with ~x86 Flag and I have a custom kernel, based on 2.6.23-gentoo-r3
If /dev/sdb1 is not encrypted (plain xfs) but /dev/sdc1 is encrypted then i can do:
| Code: | | rsync -auvb /home/ /backup/ |
without any problems. If both partitions are encrypted the I cannot do cp or rsync.
Only if i copy from an encrypted partition to an encrypted partition, then the system freezes after some seconds.
What can i do to find out what happens? Enable some logs? Is it really a CPU / Motherboard problem or could it be a software problem? with my kernel? with cryptsetup?
CPU and motherboard temperatures are fine!
I NEVER get kernel panics with the same hardware if i only use 1 encrypted (it doesnt matter if it I use sdb1 or sdc1 as my encrypted homepartition.
And I never get kernel panics if i compile something.
Please help me. I can post additional log or config files if you need them. |
