On the other hand I was able to write an email with thunderbird and sen= d it out before I had to power off the system - sysrq key alt+print+b didn't worked too. > Does trinity start w/ a random seed, so you can restart?

But because the bug occurred after 3 hours /me thinks that a simple replay with just few syscalls won't work. > "I threw random garbage at the kernel and something fell off after a > few hours" is a bit vague. ;) yes - I do know that the bug report lacks data to easy reproduce it - OTOH I thought it is better to report that then to ignore. To speed up things for fuzzy tests I do use file systems living in a tempfs. I'll change my scripts to hold at least the main log file of trinity on a hard disk and came back if I do have useful log data too. --=20 MfG/Sincerely Toralf F=C3=B6rster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
