[arch-general] is scsi hot swap broken?

[Sergey Manucharian]

Hi folks,

Just noticed after the recent update to kernel 3.3.6, an attempt to remove a SATA HDD:

  # echo scsi remove-single-device 3 0 0 0  > /proc/scsi/scsi

takes very long time:

  $ dmesg

  sd 3:0:0:0: [sdb] Synchronizing SCSI cache
  sd 3:0:0:0: timing out command, waited 360s
  sd 3:0:0:0: timing out command, waited 360s
  sd 3:0:0:0: timing out command, waited 360s
  sd 3:0:0:0: [sdb]  Result: hostbyte=0x00 driverbyte=0x00
  sd 3:0:0:0: [sdb] Stopping disk

then adding an another HDD to ANY scsi channel does not work anymore. I've checked three differeent HDDs with the same result.

The controller is :

  $ lspci | grep SATA

  00:1f.2 IDE interface: Intel Corporation N10/ICH7 Family SATA Controller [IDE mode] (rev 01)


I used to use the hot swapping frequently before, never had such a problem.

Am I missing something?


Thanks for advices/ideas.

Sergey
