Hello I am experiencing occasional lockups that seem related to my via sata controller.
Normally I get sata controller resets like this: May 19 20:10:22 [kernel] [ 809.542325] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen May 19 20:10:22 [kernel] [ 809.542339] ata1.00: cmd b0/d8:00:00:4f:c2/00:00:00:00:00/00 tag 0 cdb 0x0 data 0 May 19 20:10:22 [kernel] [ 809.542341] res 40/00:00:00:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) May 19 20:10:22 [kernel] [ 809.749359] ata1: soft resetting port May 19 20:10:22 [kernel] [ 809.910985] ATA: abnormal status 0x7F on port 0x0001ec07 May 19 20:10:22 [kernel] [ 809.921589] ATA: abnormal status 0x7F on port 0x0001ec07 May 19 20:10:22 [kernel] [ 809.928615] ata1.00: configured for UDMA/133 May 19 20:10:22 [kernel] [ 809.928658] ata1: EH complete May 19 20:10:23 [kernel] [ 810.010064] SCSI device sda: 398297088 512-byte hdwr sectors (203928 MB) May 19 20:10:23 [kernel] [ 810.010435] sda: Write Protect is off May 19 20:10:23 [kernel] [ 810.010441] sda: Mode Sense: 00 3a 00 00 May 19 20:10:23 [kernel] [ 810.012468] SCSI device sda: write cache: enabled, read cache: enabled, doesn't support DPO or FUA May 19 20:12:08 [kernel] [ 915.402338] APIC error on CPU0: 00(02) May 19 20:12:08 [kernel] [ 915.685418] APIC error on CPU0: 02(02) May 19 20:14:13 [kernel] [ 1040.624274] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen May 19 20:14:13 [kernel] [ 1040.624288] ata1.00: cmd b0/d8:00:00:4f:c2/00:00:00:00:00/00 tag 0 cdb 0x0 data 0 May 19 20:14:13 [kernel] [ 1040.624291] res 40/00:00:00:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) May 19 20:14:14 [kernel] [ 1041.596505] ata1: soft resetting port May 19 20:14:14 [kernel] [ 1041.758128] ATA: abnormal status 0x7F on port 0x0001ec07 May 19 20:14:14 [kernel] [ 1041.768872] ATA: abnormal status 0x7F on port 0x0001ec07 May 19 20:14:14 [kernel] [ 1041.775762] ata1.00: configured for UDMA/133 May 19 20:14:14 [kernel] [ 1041.775806] ata1: EH complete May 19 20:14:14 [kernel] [ 1041.893216] SCSI device sda: 398297088 512-byte hdwr sectors (203928 MB) May 19 20:14:14 [kernel] [ 1041.893598] sda: Write Protect is off May 19 20:14:14 [kernel] [ 1041.893631] sda: Mode Sense: 00 3a 00 00 May 19 20:14:14 [kernel] [ 1041.894993] SCSI device sda: write cache: enabled, read cache: enabled, doesn't support DPO or FUA May 19 20:15:09 [kernel] [ 1096.341264] APIC error on CPU0: 02(0a) Since there is an apic error message I tried to disable apic.
