My via C3 Ezra is out to lunch after big SiI3112 sata writes. dd if=/dev/zero of=/usr/zero2 bs=1024 count=100000 causes no apparent problems... dd if=/dev/zero of=/usr/zero2 bs=1024 count=500000 500000+0 records in 500000+0 records out seems to complete, but 4/5 times a process, pdflush, continues at 98% cpu. I'm using reiserfs. shells open continue to work (and I can run the command again without error), but anything that requires access to the /usr partition does not return. ...Another attempt to run the command is not returning, now dd is at 96% cpu, pdflush is at 0% cpu and top (still interactive) is the only other non-idle process. There is a problem booting too. The sata drive is seen as /dev/hdc (primary sata channel, only one on board ata channel) but linux seems to think there is a drive on the second sata channel /dev/hde, which takes 30 seconds to timeout. hde: no response (status = 0xfe) hde: no response (status = 0xfe), resetting drive hde: no response (status = 0xfe) I suspect there is a configuration to not do that, but I don't know what it is. Presently, nothing is connected to the single on board ide channel (hda, hdb), but no apparent difference when a cdrom is on hda with the hdc sata drive.
