Problems with recent (2.2.0pre5/6) kernels

[Jon Stockill]

I'm currently running slackware 3.6 with kernel 2.1.99 on a P150 system
with a 2940 scsi controller. The drives connected are as follows:

Attached devices:

Linux is installed on the 4.2GB drive.

However, kernels more recent than this (including the pre5/6 versions)
will not boot as some of the drives are not recognised (despite showing up
in the scsi bios)

Te following drives are visible:

Attached devices: 
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: HP       Model: C3725S           Rev: 6039
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 02 Lun: 00
  Vendor: HP       Model: C2490A-300       Rev: 4140
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 03 Lun: 00
  Vendor: HP       Model: HP35470A         Rev: T503
  Type:   Sequential-Access                ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 05 Lun: 00
  Vendor: HP       Model: 4.26GB A 80-886R Rev: 886R
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 06 Lun: 00
  Vendor: TANDBERG Model:  TDC 4200        Rev: =05:
  Type:   Sequential-Access                ANSI SCSI revision: 02

Therefore I have no /dev/sde1 partition, so the kernel can't mount root,
so it hangs.

Has anyone else seen this problem? Disabling scsi bus reset, or increasing
the delay after reset seems to make no difference at all.
