Public bug reported: Upon upgrading my desktop (a Shuttle SN85g4 version 2) to Edgy today, I found that it would no longer boot.
On investigation, I found that it was hanging while "Waiting for root filesystem..." I scrolled back a bit and found (copied by hand, typographical errors are possible, even probable): ata1: SATA max UDMA/100 cmd 0xE0828080 ctl 0xE082808A bmdma 0xE0828000 irq 161 ata2: SATA max UDMA/100 cmd 0xE08280C0 ctl 0xE08280CA bmdma 0xE0828008 irq 161 ata1: SATA link up 1.5 Gbps (SStatus 113) ata1: dev 0 ATA-6, max UDMA/133, [number] sectors: LBA48 ata1: qc timeout (cmd0xef) ata1: failed to set xfermode (err_mask=0x4) scsi0: sata_sil ata2: SATA link down (SStatus 0) scsi1: sata_sil The system still boots fine using the latest Dapper kernel (2.6.15-27-k7) Output from LSPCI: 00:00.0 Host bridge: nVidia Corporation nForce3 Host Bridge (rev a4) 00:01.0 ISA bridge: nVidia Corporation nForce3 LPC Bridge (rev a6) 00:01.1 SMBus: nVidia Corporation nForce3 SMBus (rev a4) 00:02.0 USB Controller: nVidia Corporation nForce3 USB 1.1 (rev a5) 00:02.1 USB Controller: nVidia Corporation nForce3 USB 1.1 (rev a5) 00:02.2 USB Controller: nVidia Corporation nForce3 USB 2.0 (rev a2) 00:05.0 Ethernet controller: nVidia Corporation nForce3 Ethernet (rev a5) 00:08.0 IDE interface: nVidia Corporation nForce3 IDE (rev a5) 00:0a.0 PCI bridge: nVidia Corporation nForce3 PCI Bridge (rev a2) 00:0b.0 PCI bridge: nVidia Corporation nForce3 AGP Bridge (rev a4) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:05.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03) 01:05.1 Input device controller: Creative Labs SB Audigy MIDI/Game port (rev 03) 01:05.2 FireWire (IEEE 1394): Creative Labs SB Audigy FireWire Port 01:06.0 FireWire (IEEE 1394): VIA Technologies, Inc.
