I don't think so because I did a lot of Googling some months ago and I've been also searching thoroughly through the mailing list archives to no avail. I have a Toshiba DynaBook V4/493PMHW laptop (lspci -vvxxx output attached) and when I compile ACPI with 'Processor support' (either with or without 'Thermal zone'), when my computer serves data through my ethernet card (a Realtek 8139) I get the following error (extracted from /var/log/syslog): May 31 01:35:33 roamer kernel: NETDEV WATCHDOG: eth0: transmit timed out May 31 01:35:33 roamer kernel: eth0: Tx queue start entry 48 dirty entry 44. May 31 01:35:33 roamer kernel: eth0: Tx descriptor 0 is 00002000. (queue head) May 31 01:35:33 roamer kernel: eth0: Tx descriptor 1 is 00002000. May 31 01:35:33 roamer kernel: eth0: Tx descriptor 2 is 00002000. May 31 01:35:33 roamer kernel: eth0: Tx descriptor 3 is 00002000. May 31 01:35:33 roamer kernel: eth0: Setting half-duplex based on auto-negotiated partner ability 0000. This doesn't happen with outbound connections, only when I act as a server. I guess it occurs when I have to send a lot of data. But just doing a ssh to my computer from another one and leaving a key pressed for a couple of lines will cause this. The communication is interrupted for maybe 10 seconds until /dev/eth0 comes up again (last line of the log). When I act as an ftp/scp server after some 5-10MB of data (maybe less) it comes to a stall. The second line can vary with dirty entries in the 80s or 100s, but always the first one is 4 numbers greater than the previous one, e.g.: May 31 01:35:33 roamer kernel: eth0: Tx queue start entry 86 dirty entry 82. When I disable 'Processor support' under ACPI this doesn't happen at all. I had this problem with 2.4.19 and now again with 2.4.20 so I suppose it went unnoticed. Is this a bug? Should I send it to the devel list? Any help greatly appreciated.
