https://bugzilla.novell.com/show_bug.cgi?id=302327#c5 --- Comment #5 from Warren Stockton <wns@comcast.net> 2007-09-20 23:02:16 MST --- I have updated to 10.3RC1 but the update kernels were also installed (so I don't know if the kernel-default-2.6.22.5-23 had the problem): # rpm -qa kernel-* kernel-source-2.6.22.5-25 kernel-vanilla-2.6.22.5-23 kernel-default-2.6.22.5-25 I still get the hang with the latest kernel. I have noticed that if I set the RTC via the BIOS setup to the correct time and then run the -default kernel until it hangs, I find than when I reboot the RTC has a wrong (corrupted) time. The RTC date appears to still be correct. I am running ntpd and wondering if this has anything to do with the kernel's sync_cmos_clock() I don't know if this ties back to issues I encounter with hwclock where it can also hang then system just reading the RTC: # hwclock --hctosys -u --test --debug hwclock from util-linux-2.13-rc2 Using /dev interface to clock. Assuming hardware clock is kept in UTC time. Waiting for clock tick... /dev/rtc does not have interrupt functions. Waiting in loop for time from /dev/rtc to change <<< hang will intermittently occur here >>> ..got clock tick Time read from Hardware Clock: 2007/10/21 00:55:51 Hw clock time : 2007/10/21 00:55:51 = 1192928151 seconds since 1969 Calling settimeofday: tv.tv_sec = 1192928151, tv.tv_usec = 0 tz.tz_minuteswest = 360 Not setting system clock because running in test mode. (intermittent hangs are encountered with both --localtime or --utc) Comparing /boot/config-2.6.22.1-16-default (which works) and /boot/config-2.6.22.5-25-default (which hangs), I notice that CONFIG_HPET_EMULATE_RTC=y is defined in 2.6.22.1-16-default This laptop (TL-56) is using hpet: # cat /sys/devices/system/clocksource/clocksource0/current_clocksource hpet The "older" laptop (TL-52) does not have hpet and uses acpi_pm as a clocksource. Booting the TL-56 with "clocksource=acpi_pm" and -default kernel does not avoid the hang. I plan to build a 2.6.22.5-25-default kernel that defines CONFIG_HPET_EMULATE_RTC=y to see if this narrows down the problem, but this will have to wait for tomorrow. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
