Hi, 2007/5/26, Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>:
What more could you possibly want? Some ATA updates? USB suspend problem
22-rc3 broke the CDROM in my Dell notebook. After I've switched to libata som time ago, I've got some delays/timeouts during boot [1]. But the drive works as expected. With 2.6.22-rc3 I've got the following messages during bootup: [ 19.343211] ata_piix 0000:00:07.1: version 2.11 [ 19.343598] scsi0 : ata_piix [ 19.344068] scsi1 : ata_piix [ 19.344426] ata1: PATA max UDMA/33 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x00010860 irq 14 [ 19.345135] ata2: PATA max UDMA/33 cmd 0x00010170 ctl 0x00010376 bmdma 0x00010868 irq 15 [ 0.653333] Marking TSC unstable due to: possible TSC halt in C2.

Is there a patch I can apply?
