Description George Akimov 2007-02-14 00:29:11 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.9) Gecko/20061206 Firefox/1.5.0.9

Description of problem:
This feature request is about adding support for 8086:25ab PCI device (Intel 6300ESB Watchdog Timer) to i8xx_tco module. I found simple patch for that, applied it and recompiled the kernel. It works. The patch is at http://marc.theaimsgroup.com/?l=linux-kernel&m=110711973917746&w=2

Version-Release number of selected component (if applicable):
2.6.9-42.0.8

How reproducible:
Always


Steps to Reproduce:
1. modprobe i8xx_tco on any Intel 6300ESB mobo (Tyan S2198 in my case)
2.
3.

Actual Results:
FATAL: Error inserting i8xx_tco (...): No such device

Expected Results:
Kernel module loads and /dev/watchdog gets created

Comment 2 Jason Baron 2007-02-28 21:29:55 UTC

ok i've added just the PCI id to this driver, can you please try the test
kernels at: http://people.redhat.com/~jbaron/bz228623/ and let me know how they
work. thanks.

Comment 3 George Akimov 2007-02-28 22:43:19 UTC

Installed kernel-2.6.9-49.watch.1.EL and loaded "modprobe i8xx_tco" on Tyan
S2198 mobo. Dmesg reports:
"i8xx TCO timer: initialized (0x0460). heartbeat=30 sec (nowayout=0)"
Ran "echo '1' >/dev/watchdog; while ((1)); do date; sleep 1; done"
Hardware reset happens in 60 seconds, not in 30 as I expected. Maybe it takes 2
missing heartbeats? In any case, thanks, it works for me.
