Bug#576913: further info on Sata raid 1 errors
Hi
I read that having acpi 2.0 enabled in bios was an issue so I disabled
this and rebooted to test (tried turning all acpi off and Linux hung
just after grub so it needs at least this I suppose).
Full version from startup:
Linux version 2.6.26-2-686 (Debian 2.6.26-21lenny4) (dannf@debian.org)
(gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25)) #1 SMP Tue
Mar 9 17:35:51 UTC 2010
2 'errors?' in start up:
ACPI Warning (tbutils-0217): Incorrect checksum in table [OEMB] - C1,
should be BC [20080321]
and
scsi 0:0:0:0: Direct-Access ATA WDC WD5000AAKS-0 05.0 PQ: 0 ANSI: 5
scsi 0:0:1:0: Direct-Access ATA WDC WD5000AAKS-0 05.0 PQ: 0 ANSI: 5

Driver 'sd' needs updating - please use bus_type methods
System took longer to boot with acpi 2.0 disabled in bios.
As soon as system up I tried dumping a database out of mySQL
mysqldump -u root -p********* --opt --databases --routines
livemuf_garage | gzip > /var/lib/mysql/raudata/livemuf_garage.sql.gz
the db is 3gb, gzipped it is 800mb.
The system never froze totally but locked at THE END of the data dump
out for ~ 5 seconds. Here is an extract from the log for the errors:

This all has me stumped. I know the hardware is fine as I have tested
hard with windows 2008. I expected much better raid performance (mysql
record inserts are intermittant / slow and reads are slow) and I have a
feeling this is all relating to the same thing but I cannot identify
what it is
Kind regards
