SOT: For hardware vendors.. dealing with new hardware

[Stephen Smoogen]

Semi Off Topic

For hardware vendors who are dealing with putting RHL-7.x onto newer
hardware.. I have been working getting aic79xx into the last errata
kernels. After 2 days.. I have come to remember why I am not a kernel
developer :). 

Somewhere between the changes in 2.4.20-18 and 2.4.20-24 the driver
source code from Adaptec or Justin Gibbs site will compile, but we get
consistent kernel panics when running. The system dies in about 2-4
minutes with something similar to this:

 (scsi1:A:1:0): SCB 129 Packetized Status Overrun>>>>>>>>>>>>>>>>>> Dump
Card State Begins <<<<<<<<<<<<<<<<<
 scsi1: Dumping Card State at program address 0x295 Mode 0x11
 Card was paused
 HS_MAILBOX[0x0] INTCTL[0x80] SEQINTSTAT[0x0] SAVED_MODE[0x11]
 DFFSTAT[0x0] SCSISIGI[0x24] SCSIPHASE[0x1] SCSIBUS[0x0]
 LASTPHASE[0x1] SCSISEQ0[0x0] SCSISEQ1[0x12] SEQCTL0[0x10]
 SEQINTCTL[0x8] SEQ_FLAGS[0xc0] SEQ_FLAGS2[0x4] SSTAT0[0x0]
 SSTAT1[0x19] SSTAT2[0x0] SSTAT3[0x80] PERRDIAG[0xc0]
 SIMODE1[0xa4] LQISTAT0[0x0] LQISTAT1[0x0] LQISTAT2[0x0]
 LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x81]
  
Not expecting anyone on the list to have a fix... more of a gotcha to
look out for clients who have to have old release on new hardware.
