: this is a report of a malfunction of my portable system running
: Linux 1.2.13 on a Texas Instruments 4000M with a FSCSI-2 Quantum
: Daytona 514S disk and a Toshiba CD-ROM; the TI4000M has an Adaptec
: 152x chipset, with base 0x340, IRQ 11, SCSI ID 7 and both reconnect
: and parity enabled.
I to am getting similar errors from a brand-new IOmega Zip drive and a
recient aha1522a. I am mounting my zip drive (/dev/sda) on /usr/src,
and intermittently (once every day or two) I get a timeout that leads
to a "reset for secnond half of retries" afterwhich the device
appears to be locked up. The process that "caused" the error hangs
in a 'D' state, as does any future process that attempts to access the
disk.
Is this a hardware problem, software, both, neither? I have tried to
increase the ABORT_TIMEOUT to (5*HZ) from (5*HZ/10), and this seems
to increase the amount of time before the drive locks up.
I have noticed this behaviour with 1.2.12 and 1.3.17. I have just
rebooted with 1.3.18. All monolithic, all a.out format (kernel and
all exe's)
Hardware info from log (log header zaped to make it more readable,
available on request).
