Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal

AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]

yet ;)
Hardware Environment: hp nc8430
Software Environment:
Problem Description:
booting with 2.6.24-rc4 causes the following errors/messages while initializing
sata/ahci:
[ 26.494962] ahci 0000:00:1f.2: version 3.0

irq 219
[ 28.137999] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
next comes the first failure:
[ 28.140561] ata1.00: ACPI cmd b1/c1:00:00:00:00:a0 failed (Emask=0x1
Stat=0x51 Err=0x04)
[ 28.141091] ata1: failed to recover some devices, retrying in 5 secs
[ 34.786461] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 34.789004] ata1.00: ACPI cmd b1/c1:00:00:00:00:a0 failed (Emask=0x1
Stat=0x51 Err=0x04)
then the second failure:
[ 34.789534] ata1.00: ACPI on devcfg failed the second time, disabling
(errno=-5)
[ 34.789753] ata1.00: revalidation failed (errno=1)
[ 34.789914] ata1: failed to recover some devices, retrying in 5 secs
[ 41.434924] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 41.437002] ata1.00: configured for UDMA/100
after this the driver works and boot proceeds fine. so it's not a show stopper
for me but something isn't right. also i'm not sure if it's really an ACPI
problem, but it was some ACPI command that was last issued/logged so i thought
it'd put this under ACPI, feel free to reclassify. if you need any extra info,
let me know but i'd like to avoid bisecting if possible.
Steps to reproduce: just compile/boot with 2.6.24-rc4.
