Hangs with 2.4.23-preX kernels probabòy related to the 8139cp driver

Hi all,
I'm experiencing hangs with 2.4.23-pre kernels when using the network with the said driver. The last kernel that works is the 2.4.22-pre8. I noticed that during this versions there where updates to the eth. drivers. Unfortunately the kernel does not give any error, just the pc does not respond to pings, the cursor on screen stops blinking. Tried with sysrq enabled too but nothing on logs. I can reliabily reproduce this just doing something network intensive, eg. accessing a remote desktop during a full kernel download ;)
Sorry for this terse info, if you need any other info just ask. And please CC me on replies as I'm not subscribed to the list.

Thanks,
Fredi
