also fails with -rc5 I was wating for, previous rcs not tested
Distribution: Bluewhite64 (64 bits slackware) Hardware Environment: Athlon64 X2 / Ali 1689 north 1563 south
+ bt848 v4l + PATA and SATA disk (SATA on sata_uli) Seems to be related to sata disk detection (see below).

Software Environment:
none

Problem Description:
the computer freeze totally at boot after SATA disk detection.
I append 2.6.25.4 dmesg, lspci and lsusb.
The CPU is not 100% (otherwise I could hear the fan going crazy), the keayboard is dead (unable to scroll the console up or down). Nothings happen.

The console shows somethings similar to the 2.6.25.4 logs, but hangs after those lines:
hda: cache flushes not supported
hda: hda1 hda2
hdd: ATAPI 40X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache Uniform CD-ROM driver Revision: 3.20
Driver 'sd' needs updating - please use bus_type methods sata_uli 0000:00:0e.1: version 1.3
ACPI: PCI Interrupt 0000:00:0e.1[A] -> GSI 19 (level, low) -> IRQ 19 scsi0 : sata_uli
scsi1 : sata_uli
ata1: SATA max UDMA/133 cmd 0xf80 ctl 0xf00 bmdma 0xd880 irq 19
ata2: SATA max UDMA/133 cmd 0xe80 ctl 0xe00 bmdma 0xd888 irq 19
ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

<-- here, 2.6.24 hangs -->

normal way for 2.6.25 :

ata1.00: ATA-7: ST3200826AS, 3.06, max UDMA/133 ata1.00: 390721968 sectors, multi 16: LBA48 NCQ (depth 0/32) ata1.00: configured for UDMA/133
ata2: SATA link down (SStatus 0 SControl 300)
scsi 0:0:0:0: Direct-Access ATA ST3200826AS 3.06 PQ: 0 ANSI: 5
sd 0:0:0:0: [sda] 390721968 512-byte hardware sectors (200050 MB) sd 0:0:0:0: [sda] Write Protect is off
sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00

Steps to reproduce:
Boot my PC :-)
I guess any sata_uli device may hang the same way?

yup, I'd say that the ata code (or something very nearby) killed your box.

This is a post-2.6.25 regression.
