Dear Caldera Customer, Support Level Supplement (SLS) ptf7049j, the Adaptec DD17 adsl HBA Supplement, supersedes all previous versions of ptf7049 and all versions of SLS ptf3124. SLS ptf7049f addresses the following issues: - The adsl driver as supplied in ptf7049f had a timeout problem. - The adsl driver hangs in adsl_getblk under heavy disk I/O. - Failover of the OSR5000 controller causes an ODM mirror break. After this occurs, the rebuild time is exceptionally long. - Performing an mccntl -l command causes a panic with adsl. SLS ptf7049g addresses the following issues found with other versions of UnixWare 7 and SCO UnixWare: - The performance of ARCserve tape operations is poor on systems using an adsl HBA to control the tape unit. - On some tape devices it may not be possible to restore data from a backup created by ARCserve. - Poor performance using Quad controller (4944W). - Data Overrun/Underrun errors. - Tape drive not recognized after upgrading to SCO UnixWare 2.1.3. - Appearance of these error messages: WARNING: adsl: Data Overrun or Underrun [C1007024] (ha/targetID/lun 0/5/0) WARNING: (adsl, 2) Adaptec PCI SCSI: C1, SDI registry failure -157 SLS ptf7049i addresses the following issue: erg711348 fz511492 Adaptec 3944 is a dual channel differential SCSI HBA hanging or panicing system SLS ptf7049j additionally addresses the following issue: Panic in adsl_sgdone.
