Subject: [2.6.1{5,6,7}at least] Multiple cron hang in fork on reboot
I have been suffering from this problem intermittently at least since
2.6.15. Just rebooted 2.6.17.9 and it has happened again.
Symptoms: After a reboot I get multiple cron processes stuck in fork.
Loadavg rises. Sometimes the stuck processes clear in about 12 hours, but often the
system crashes and reboots.
This time I have unwind info compiled in and have dumped the active task
list (see below).
System is Acer aspire 1350, debian testing. Config attached.
Let me know if you need any more info.
Thanks,
Mark
