Re: Installation loop because of a 53c810 SCSI adapter

The SYM driver do not support some old 53c810 chips, it might be what
you are seeing, use the NCR driver for thoose.

If that does not work, ask on linux-scsi@vger.kernel.org mailing list.
Have you checked your cabling and terminations?

Strange that you get the ncr53c8xx_reset message, have you copied it
wrong, or are you using the ncr driver?

  $ grep ncr53c8xx_reset *.c
  ncr53c8xx.c:int ncr53c8xx_reset(Scsi_Cmnd *cmd, unsigned int reset_flags)
  ncr53c8xx.c:int ncr53c8xx_reset(Scsi_Cmnd *cmd)
  ncr53c8xx.c:    printk("ncr53c8xx_reset: pid=%lu reset_flags=%x serial_number=%ld serial_number_at_timeout=%ld\n",
  ncr53c8xx.c:    printk("ncr53c8xx_reset: command pid %lu\n", cmd->pid);
  $ grep sym53c8xx_reset *.c
  sym53c8xx.c:int sym53c8xx_reset(Scsi_Cmnd *cmd, unsigned int reset_flags)
  sym53c8xx.c:int sym53c8xx_reset(Scsi_Cmnd *cmd)
  sym53c8xx.c:    printk("sym53c8xx_reset: pid=%lu reset_flags=%x serial_number=%ld serial_number_at_timeout=%ld\n",
  sym53c8xx.c:    printk("sym53c8xx_reset: command pid %lu\n", cmd->pid);

For 2),
  cp ..../disks-i386/current/images-1.44/compact/kernel-config ..../linux/.config
  choose NCR driver instead of SYM
  mount resque floopy as /mnt
  build and copy the bzImage to rescue floppy as linux
  cd /mnt; ./rdev.sh
  cd; umount /mnt
  Try it out
