[Bug 57096] after Squid logrotate system hangs

[Martin Hofbauer]

Public bug reported:

Binary package hint: linux-image-2.6.15-26-386

Environment:
Squid 2.5.STABLE12, Ubuntu 6.0.6, Kernel: 2.6.15-26-i386

Now this is the 2nd time this happened within a week.
After the weekend I found the system in a locked situation. I rebooted
and found following in the log files:

Immediatly after a logrotate of Squid there arethousends of (the same) entries in
the syslog and message file:

Aug 20 07:35:32 chef squid[5284]: storeDirWriteCleanLogs: Starting... 
Aug 20 07:35:32 chef squid[5284]:   Finished.  Wrote 7209 entries. 
Aug 20 07:35:32 chef squid[5284]:   Took 0.0 seconds (2601587.9 entries/sec). 
Aug 20 07:35:32 chef squid[5284]: logfileRotate: /var/log/squid/store.log 
Aug 20 07:35:32 chef squid[5284]: logfileRotate: /var/log/squid/access.log 
Aug 20 07:35:32 chef kernel: [17502033.772000] __find_get_block_slow() failed.

...
..

3 Seconds and thousends(millions?) of such messages later there is no more
entry in any log  ( and I assume , that at this time the system has locked )

Additional informaiton: 
1.) that this system running fine for about 2 month ( after upgrading to Ubuntu
6.06)  and 
2.) This system had about 5-10 power cuts within a day . 
So, maybe some files  or squid cache is corrupt

But how do I find this out, the system is running fine now !

What does this kernel message mean ?
