That may or may not make a difference. But it *should* work. Are there any other error messages in dmesg? AHA! Appears this is an initialization problem, when I cold-boot from power-off all is well. When I warm-boot from some other OS (w2K-problem) is when it fails to load. Looks like other OS is leaving the chip in an un-expected state. Also seeing similar wierdnesses with the mini-PCI eepro100 card. This could easily be a BIOS bug on that machine, unfortunately. W2K sometimes powers devices down in a way Linux has trouble powering back up. Sometimes it even sets the MAC address for networkcards to all 00:00's while storing the real address in it's registry. I'd hardly call this a Linux bug... hate to reopen things labeled as "notabug", but this is definitely a kernel related problem. ran into it on my gf's T20 and it definitely wasnt being left in a bad state by any other OS. the module claimed to modprobe several times, but never actually did. resolution: installed rawhide kernel, driver loads happily. |
