https://bugzilla.novell.com/show_bug.cgi?id=208818 ------- Comment #3 from seife@novell.com 2006-11-23 07:11 MST ------- Greg, i have a "feeling" that the driver is getting worse with beta2+ and rc1. I more often get total lockups on network problems or sometimes just when using the card. I do not see any lockups on this machine when the nozomi card is not plugged in, so i attribute it to this driver :-) Has anything changed in the driver lately? OTOH it is happening not very often (but the last few days it happened ~3 times, weeks before were without problems), so it might be a coincidence. Just to let you know :-) -- 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, or are watching someone who is.

I will try to get some more time to work on this after 10.2 is out... -- 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, or are watching someone who is.

All without anything changed. So it is some not-easily-triggered bug probably. Anyway, the driver still oopses the kernel when i pull out the card in SLED10SP1Beta1. Gerald now also has such a card and surely wants it to work well in SLE?10sp1 :-) -- 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, or are watching someone who is.

Note that i needed to insert and eject the card manually in this machine with "pccardctl insert/eject" because it apparently does not get the hotplug event from yenta. This is a different bug, which is already reported (and it works in 10.2). Just that you know why the card_eject file was the last sysfs file :-) It crashes on other, better behaving machines, too, but those are not online now. -- 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, or are watching someone who is.
