Public bug reported:

Hi,

My computer is a Dell T7400 with an  Intel 631xESB/632xESB/3100 Ultra
ATA storage controller.

I cannot boot Karmic using this old kernel as mountall needs a newer kernel.
If I use kernel 2.6.31.14  sooner or later the system crashes (disk errors):

lspci -vvn :
00:1f.2 SATA controller [0106]: Intel Corporation 631xESB/632xESB SATA AHCI 
Controller [8086:2681] (rev 09) (prog-if 01)
        Subsystem: Dell Device [1028:021d]

syslog kernel 2.6.31.14

Oct 31 18:01:44 T7400 kernel: [  389.148073]         00 00 00 00 00 00 

I get the same error message when using smartctl.

If I compare the syslog using kernel 2.6.24.24 (which works perfectly) and 
kernel 2.6.31.14 the main difference are:
2.6.24.24:
EXT3-fs: mounted filesystem with ordered data mode.
2.6.31.14:
EXT3-fs: mounted filesystem with writeback data mode.

The following lines do not appear while using kernel 2.6.24.24
mptsas 0000:05:00.0: PCI INT A -> GSI 56 (level, low) -> IRQ 56    
xor: automatically using best checksumming function: pIII_sse

xor: using function: pIII_sse (9901.000 MB/sec)
device-mapper: dm-raid45: initialized v0.2594b


Could someone kindly help me ?
