Description of problem: Periodically when pressing the reset button on a Pentium 3 cPCI blade which is connected to a dual IDE disk drive carrier with SCSI interface, the boot hangs with the following timeout messages: sym53c1010-66-0: rev 0x1 on pci bus 1 device 4 function 0 irq 26 sym53c1010-66-0: Symbios format NVRAM, ID 7, Fast-80, Parity Checking sym53c1010-66-0: on-chip RAM at 0xfe000000 sym53c1010-66-0: restart (scsi reset). sym53c1010-66-0: handling phase mismatch from SCRIPTS. sym53c1010-66-0: Downloading SCSI SCRIPTS. sym53c1010-66-1: rev 0x1 on pci bus 1 device 4 function 1 irq 27 sym53c1010-66-1: Symbios format NVRAM, ID 7, Fast-80, Parity Checking sym53c1010-66-1: on-chip RAM at 0xfe002000 sym53c1010-66-1: restart (scsi reset). sym53c1010-66-1: handling phase mismatch from SCRIPTS. sym53c1010-66-1: Downloading SCSI SCRIPTS. scsi0 : sym53c8xx-1.7.3c-20010512 scsi1 : sym53c8xx-1.7.3c-20010512 blk: queue f7b6c018, I/O limit 4095Mb (mask 0xffffffff) scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 0, lun 0 Inquiry 00 00 00 ff 00 sym53c8xx_abort: pid=0 serial_number=1 serial_number_at_timeout=1 SCSI host 0 abort (pid 0) timed out - resetting SCSI bus is being reset for host 0 channel 0. sym53c8xx_reset: pid=0 reset_flags=2 serial_number=1 serial_number_at_timeout=1 sym53c1010-66-0: restart (scsi reset). sym53c1010-66-0: handling phase mismatch from SCRIPTS. sym53c1010-66-0: Downloading SCSI SCRIPTS.

SCSI host 0 abort (pid 2) timed out - resetting SCSI bus is being reset for host 0 channel 0. The problem isn't cleared up until the disk carrier is reseated. Reseating the Pentium 3 blade doesn't clear up the problem. Problem has never been displayed when performing Linux reboot command. Version-Release number of selected component (if applicable): kernel-smp-2.4.18-10 How reproducible: kernel-smp-2.4.18-10 Steps to Reproduce: 1. Press reset button 2. 3. Actual results: Keep getting the following where XXX increments by 1 SCSI host 0 abort (pid XXX) timed out - resetting SCSI bus is being reset for host 0 channel 0. sym53c8xx_reset: pid=XXX reset_flags=2 serial_number=XXX serial_number_at_timeout=XXX sym53c1010-66-0: restart (scsi reset). sym53c1010-66-0: handling phase mismatch from SCRIPTS. sym53c1010-66-0: Downloading SCSI SCRIPTS. Expected results: The disk carrier should be recognized as follows: blk: queue f7b6c018, I/O limit 4095Mb (mask 0xffffffff) Vendor: ADTRON Model: SC6x2 Q16015_045 Rev: 2s04 Type: Direct-Access ANSI SCSI revision: 02 blk: queue f7541e18, I/O limit 4095Mb (mask 0xffffffff) Attached scsi disk sda at scsi0, channel 0, id 0, lun 0 sym53c1010-66-0-<0,0>: phase change 6-7 9@003f34b8 resid=5. sym53c1010-66-0-<0,*>: FAST-10 SCSI 10.0 MB/s (100.0 ns, offset 7) SCSI device sda: 39070080 512-byte hdwr sectors (20004 MB) sda: sda1 sda2 Additional info:
please try the erratum kernel as well. In addition we ship an alternate driver (sym53c8xx_2) that might have improved behavior for this case. However it really sounds like the hardware is getting confused by the reset button's power break
