Bug ID: 204554
Summary: Intel 6300ESB SATA150 cannot find disk and boot rerun
of 127391
Product: Base System
Version: 9.3-RELEASE
Hardware: i386
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
I reported kern/127391 back when I upgraded to 6.3 and 7.1. A patch was
re-discovered after being lost. See
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=127391
for the details. I had to patch sys/dev/ata/chipsets/ata-intel.c to increase
the DELAY value in the reset routine.

mask |= (1 << smap[1]);
pci_write_config(parent, 0x92,
pci_read_config(parent, 0x92, 2) & ~mask, 2);
! DELAY(100);
pci_write_config(parent, 0x92,
pci_read_config(parent, 0x92, 2) | mask, 2);
I did notice that the GENERIC kernel worked fine when the console was
redirected to the serial port which led me to think to keep increasing the
DELAY value until it started working.
