Hello, I keep seeing the following in my logs, should i be worried?: Sep 4 03:01:29 ns2 kernel: DOH! ata_alloc_request failed! Sep 4 03:01:29 ns2 kernel: FAILURE - out of memory in ata_raid_init_request Sep 4 03:01:29 ns2 kernel: g_vfs_done():ar0s1f[WRITE(offset=107303043072, length=16384)]error = 5 The disks seems fine as far as smartmontools can tell and there is no visible data loss or corruption. This an an Opteron system running in AMD64 mode on a Nvidia motherboard using the on-board ata raid. I've seen some posts from other people complaining about this, but no real answer as to the cause of the problem. Thanks. --- atapci0: <nVidia nForce CK804 UDMA133 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xe800-0xe80f at device 6.0 on pci0 ata0: <ATA channel 0> on atapci0 ata1: <ATA channel 1> on atapci0 atapci1: <nVidia nForce CK804 SATA300 controller> port 0x9f0-0x9f7,0xbf0-0xbf3,0x970-0x977,0xb70-0xb73,0xd400-0xd40f mem 0xfebfc000-0xfebfcfff irq 21 at device 7.0 on pci0 ata2: <ATA channel 0> on atapci1 ata3: <ATA channel 1> on atapci1 atapci2: <nVidia nForce CK804 SATA300 controller> port 0x9e0-0x9e7,0xbe0-0xbe3,0x960-0x967,0xb60-0xb63,0xc000-0xc00f mem 0xfebfb000-0xfebfbfff irq 22 at device 8.0 on pci0 ata4: <ATA channel 0> on atapci2 ata5: <ATA channel 1> on atapci2 ad4: 114473MB <Seagate ST3120813AS 3.AAD> at ata2-master SATA300 ad6: 114473MB <Seagate ST3120813AS 3.AAD> at ata3-master SATA300 ar0: 114473MB <nVidia MediaShield RAID1> status: READY ar0: disk0 READY (master) using ad4 at ata2-master ar0: disk1 READY (mirror) using ad6 at ata3-master
