Yesterday, I also started with a 2.6.16-rc6 kernel (with the 2 op-code info
patches).
The first two busy messages already are logged at boot up:
kernel: [ 74.254530] ata5: status=0xd0 { Busy }
that happens right after the raids have been set up.
With 2.6.15.4 there never are any messages of the mentioned kind during
boot-up, but only e.g. with kmail retrieval or postgres insert&delete writing
to the volume group the raid6 with the 3 ot of 7 disks on Adaptec 1420SA.
Then, when the reiser filesystem on the vg made up of the raid6 is mounted, a
couple of busy messages and these three abnormal status messages are logged:
kernel: [152.627933] ata4: status=0xd0 { Busy }
kernel: [152.740934] ata3: status=0xd0 { Busy }
kernel: [152.750990] ATA: abnormal status 0xD0 on port 0xFFFFC2000092211C
kernel: [152.761021] ATA: abnormal status 0xD0 on port 0xFFFFC2000092211C
kernel: [152.771052] ATA: abnormal status 0xD0 on port 0xFFFFC2000092211C
This is followed later (caused by nothing known to me, but maybe still the
mounting? or smb starting?):
kernel: [182.687864] ata3: Entering mv_eng_timeout
kernel: [182.687871] mmio_base ffffc20000900000 ap ffff81007f4fc470 qc
ffff81007f4fc9a8 scsi_cmnd ffff81007a0bcd40 &cmnd ffff81007a0bcdb0
kernel: [182.814361] ata3: status=0x50 { DriveReady SeekComplete }
kernel: [182.814364] ata3: error=0x01 { AddrMarkNotFound }
kernel: [183.694148] Assertion failed! qc->flags &
ATA_QCFLAG_ACTIVE,drivers/scsi/libata-core.c,ata_qc_complete,line=3635
kernel: [183.694157] ata3: status=0x50 { DriveReady SeekComplete }
kernel: [183.694159] ata3: error=0x01 { AddrMarkNotFound }
Then at the prompt after login, I typed find /nobak/ > somefile (/nobak is as
softlink to a directory on the raid6 with 184000 entries returned by find )
which takes a moment (7sec?) on 2.6.15.4 and does not trigger any log
messages.
With 2.6.16-rc6 it takes about 7 minutes (from 16:42:29 to 16:49:41)
and about 14 of the following log messages blocks being logged every ~30
seconds:
kernel: [245.189337] ata3: Entering mv_eng_timeout
